Would extending my mortgage cause the terms to be re-negotiated?
Run the numbers in advance. Understand what are the current rates for an additional 2nd mortgage, what are the rates for a brand new mortgage that will cover the additional funds. Understand what they are for another lender.  Estimate the amount of paperwork involved in each option (new first, new 2nd, and new lender). Ask the what are the options they can offer you. Because you have estimated the costs in money and time for the different options, you can evaluate the offer they make. What they offer you can range from everything you want to nothing you would accept. What they offer will depend on several factors: Do they care to keep you as a customer?; Do they expect you to walk away?; are they trying to get rid of mortgages like the one you have?; Can they make more money with the plan they are offering you? You will be interested in the upfront costs, the monthly costs, and the amount of time required for the process to be completed.
"We payed off our Mortgage early...at first in small extra payments to principal, and finally a lump sum.  Each extra payment to principal reduced the balance, and reduced every payment going forward.  I have, somewhere, an excel spreadsheet where I tracked this...  - =CUMIPMT((interestRate/12),term,pymtNumber,balance,balance,0) computed the interest payment due  - =currentPrincipal + CUMIPRINTresultAbove computed the monthly principal payment Occasionally I would update the month-ending Principal balance against what the mortgage company told me.  It was usually off by a little.   My mortgage company required me to specifically contact them for a payoff amount before I wrote the final check.   I've never heard of a mortgage where prepayment of all expected interest following the original schedule is required.  I would guess it is against federal (US) law.  Lets think about that for a moment...  out of ""interest"", I recently computed that for our 30 year loan at 6-5/8% on about 145, we payed a total of 106000 in interest.  That include a refi to 4-7/8 10-years in to a 15-year loan, and paying it off 20 years after the original loan was granted. As far as not paying all the theoretical interest due...  - If they get a fixed dollar amount of service interest back, there's no incentive to me to pay on-time.  I owe the same amount if I pay it today or if I pay it 6 months late, after I gambled the mortgage money and finally won.  (yea, I know they could write the mortgage to penalize me for paying late, but I'm ignoring that)  - if you were requried to pay off all the interest that might accrue, how could you ever sell your home, or refinance, for that matter?  When I refi'd, the new holder payed the old holder 98,000.  If the original holder had required prepayment of all the interest that would be accrued to the original schedule, the new mortgage would've been 200k.  It would just never be a good deal to buy a home if mortgages worked under that term. I have had a car loan that worked differently -- they pre-computed the total interest due and then divided it over the term of the loan equally.  I could pay off early and they stopped collecting interest." "Yes, it's unreasonable to think the prices will drop 10-20% in that time frame.  Housing prices are not an equation that can can be solved to ""home prices are X% overvalued."" You have 3 answers so far, Quanty's ""prices are inversely proportional to rates,"" Rob's ""there's no strong correlation between interest rates and house prices,"" and MB's, ""rising interest rates create downward pressure on housing prices."" Any research into price history had better take every other variable into account. Articles that look at rates vs price don't always address a key item, income. Say we agree that the data show your city to be 10% too high. But if sellers like their high price and have some 'dig my heels in' power, prices won't drop. The seller simply stays put, and the supply/demand curves result not in a lower price, but in less supply. And the effect is to change the demographic of that area, i.e. attracting higher income earners.  Rob linked to an article with a nice set of charts. One chart showing the US30 yr fixed rate and 'Real House Prices'. What results is a chart that can refute the relationship between rates and prices. But that would ignore an historical point that's too important to forget. The tumble that started in Jan '06 had nothing to do with the 30 year rate. It was the result of a series of insane financial products including 'interest only option ARMs' which permitted buyers to get approved for a purchase based on a payment that wasn't fixed, and would change to a fully amortizing mortgage at a higher rate that was unaffordable. A product that was a financial time bomb. Canada Banks offered no such product, and when the US market got pneumonia, Canada experienced a mild cold. With respect to any answers that offer US centric data to prove any hypothesis, I don't feel such comparisons are appropriate.  Correlations, and the data used to prove them are an interesting thing. I can suggest that you take the US 30 year rate, along with our median income, or rather 25% of monthly median income. Calculate the mortgage that results. This translates nicely to the home a median family can afford. And I claim that long term this is the equilibrium price of that median home. But supply/demand has another factor, 'stickyness' or the more technical term, 'inelasticity of demand.' This means that for example, a 10% increase in the price of cigarettes does not cause a 10% drop in consumption. Each and every good has its own elasticity, and in the case of housing, a rise in cost would certainly impact the marginal buyers, but others will simply adjust their budgets. Not all buyers were planning to hit the bank's limit on what they could afford, so the rise doesn't change their mind, just their budget.  Last - I know that Canada does not have a 30 year mortgage, most common is a 5 year rate with 30 year amortization. (correction/clarification, anyone?) The effect of this is less volatility in the market, since I believe your rates are not poised for the 2.5% to 4% jump implied by another response. Small increases can be absorbed.  In a beautiful coincidence, the Federal Reserve Board sent me a link to The Interest Rate Elasticity of Mortgage Demand: Evidence From Bunching at the Conforming Loan Limit. It's a bit long but a worthwhile look at how the correlation isn't as instant as some might think." "A mutual fund's return or yield has nothing to do with what you receive from the mutual fund. The annual percentage return is simply the percentage increase (or decrease!) of the value of one share of the mutual fund from January 1 till December 31. The cash value of any distributions (dividend income, short-term capital gains,  long-term capital gains) might be reported separately or might be included in the annual return.  What you receive from the mutual fund is the distributions which you have the option of taking in cash (and spending on whatever you like, or investing elsewhere) or of re-investing into the fund without ever actually touching the money. Regardless of whether you take a distribution as cash or re-invest it in the mutual fund, that amount is taxable income in most jurisdictions. In the US, long-term capital gains are taxed at different (lower) rates than ordinary income, and I believe that long-term capital gains from mutual funds are not taxed at all in India. You are not taxed on the increase in the value of your investment caused by an increase in the share price over the year nor do you get deduct the ""loss"" if the share price declined over the year. It is only when you sell the mutual fund shares (back to the mutual fund company) that you have to pay taxes on the capital gains (if you sold for a higher price) or deduct the capital loss (if you sold for a lower price) than the purchase price of the shares. Be aware that different shares in the sale might have different purchase prices because they were bought at different times, and thus have different gains and losses.  So, how do you calculate your personal return from the mutual fund investment? If you have a money management program or a spreadsheet program, it can calculate your return for you. If you have online access to your mutual fund account on its website, it will most likely have a tool called something like ""Personal rate of return"" and this will provide you with the same calculations without your having to type in all the data by hand. Finally, If you want to do it personally by hand, I am sure that someone will soon post an answer writing out the gory details." "I am lucky enough to have chosen a flexible mortgage that allows me to change payment amounts at certain, very lenient intervals (to a minimum amount).  So when I was laid off, the first thing I did was call my bank to lower my payments to a level that allowed me some breathing room, at my new, lower income.  If and when my family's income increases, I'll re-adjust my payments to a higher amount.   But if you're concerned about the ""what if""s in this economy, I'd definitely choose a mortgage that allows for flexibility so that you don't lose your house if you don't have to, particularly if your situation is temporary." "First off; I don't know of the nature of the interpersonal relationship between you and your roommate, and I don't really care, but I will say that your use of that term was a red flag to me, and it will be so to a bank; buying a home is a big deal that you normally do not undertake with just a ""friend"" or ""roommate"". ""Spouses"", ""business partners"", ""domestic partners"" etc are the types of people that go in together on a home purchase, not ""roommates"". Going ""halvsies"" on a house is not something that's easily contracted; you can't take out two primary mortgages for half the house's value each, because you can't split the house in half, so if one of you defaults that bank takes the house leaving both the other person and their bank in the lurch. Co-signing on one mortgage is possible but then you tie your credit histories together; if one of you can't make their half of the mortgage, both of you can be pursued for the full amount and both of you will see your credit tank. That's not as big a problem for two people joined in some other way (marriage/family ties) but for two ""friends"" there's just way too much risk involved. Second, I don't know what it's like in your market, but when I was buying my first house I learned very quickly that extended haggling is not really tolerated in the housing market. You're not bidding on some trade good the guy bought wholesale for fifty cents and is charging you $10 for; the seller MIGHT be breaking even on this thing. An offer that comes in low is more likely to be rejected outright as frivolous than to be countered. It's a fine line; if you offer a few hundred less than list the seller will think you're nitpicking and stay firm, while if you offer significantly less, the seller may be unable to accept that price because it means he no longer has the cash to close on his new home. REOs and bank-owned properties are often sold at a concrete asking price; the bank will not even respond to anything less, and usually will not even agree to eat closing costs. Even if it's for sale by owner, the owner may be in trouble on their own mortgage, and if they agree to a short sale and the bank gets wind (it's trivial to match a list of distressed mortgaged properties with the MLS listings), the bank can swoop in, foreclose the mortgage, take the property and kill the deal (they're the primary lienholder; you don't ""own"" your house until it's paid for), and then everybody loses. Third, housing prices in this economy, depending on market, are pretty depressed and have been for years; if you're selling right now, you are almost certainly losing thousands of dollars in cash and/or equity. Despite that, sellers, in listing their home, must offer an attractive price for the market, and so they are in the unenviable position of pricing based on what they can afford to lose. That again often means that even a seller who isn't a bank and isn't in mortgage trouble may still be losing thousands on the deal and is firm on the asking price to staunch the bleeding. Your agent can see the signs of a seller backed against a wall, and again in order for your offer to be considered in such a situation it has to be damn close to list. As far as your agent trying to talk you into offering the asking price, there's honestly not much in it for him to tell you to bid higher vs lower. A $10,000 change in price (which can easily make or break a deal) is only worth $300 to him either way. There is, on the other hand, a huge incentive for him to close the deal at any price that's in the ballpark: whether it's $365k or $375k, he's taking home around $11k in commission, so he's going to recommend an offer that will be seriously considered (from the previous points, that's going to be the asking price right now). The agent's exact motivations for advising you to offer list depend on the exact circumstances, typically centering around the time the house has been on the market and the offer history, which he has access to via his fellow agents and the MLS. The house may have just had a price drop that brings it below comparables, meaning the asking price is a great deal and will attract other offers, meaning you need to move fast. The house may have been offered on at a lower price which the seller is considering (not accepted not rejected), meaning an offer at list price will get you the house, again if you move fast. Or, the house may have been on the market for a while without a price drop, meaning the seller can go no lower but is desperate, again meaning an offer at list will get you the house. Here's a tip: virtually all offers include a ""buyer's option"". For a negotiated price (typically very small, like $100), from the moment the offer is accepted until a particular time thereafter (one week, two weeks, etc) you can say no at any time, for any reason. During this time period, you get a home inspection, and have a guy you trust look at the bones of the house, check the basic systems, and look for things that are wrong that will be expensive to fix. Never make an offer without this option written in. If your agent says to forego the option, fire him. If the seller wants you to strike the option clause, refuse, and that should be a HUGE red flag that you should rescind the offer entirely; the seller is likely trying to get rid of a house with serious issues and doesn't want a competent inspector telling you to lace up your running shoes. Another tip: depending on the pricepoint, the seller may be expecting to pay closing costs. Those are traditionally the buyer's responsibility along with the buyer's agent commission, but in the current economy, in the pricepoint for your market that attracts ""first-time homebuyers"", sellers are virtually expected to pay both of those buyer costs, because they're attracting buyers who can just barely scrape the down payment together. $375k in my home region (DFW) is a bit high to expect such a concession for that reason (usually those types of offers come in for homes at around the $100-$150k range here), but in the overall market conditions, you have a good chance of getting the seller to accept that concession if you pay list. But, that is usually an offer made up front, not a weapon kept in reserve, so I would have expected your agent to recommend that combined offer up front; list price and seller pays closing. If you offer at list you don't expect a counter, so you wouldn't keep closing costs as a card to play in that situation." Sounds fishy - taking out more debt to pay the main mortgage down faster? There are a couple of issues I can see: I would think that a much more sensible strategy with a lot less risk is to save up extra cash and send your lender a check every quarter or six months. That's why they're taking the deal. But it's not like they completely stole all that money. I don't have any stats, but I'd assume most of those people who got their loans are still in their homes. (Sorry, I could be way off. Please correct) But they still are bastards for not letting me refinance. Could have just been because they saw this penalty coming. The principal and interest are fixed, no matter how much money you throw at them. This is not correct. If I pay an extra $1000 in principal this month, then my mortgage balance is decreased. So slightly less interest accrues before my next payment. That means my next payment will be slightly more toward principal and slightly less toward interest than it would have been if I hadn't made an extra principal payment. This means that my principal will eventually drop to zero earlier than it would have if I had not made the extra payment, and I will end up making fewer total payments than I would have without the extra principal payments. Of course, the effect is even stronger if I make regular extra payments rather than a single one. Like paying off any debt, you can consider this payment essentially a risk free investment paying whatever is the interest rate on that debt. You know that by making this payment, you reduce your interest payments over the coming years by the interest rate on that amount.  Edit: In comments you said, you will pay your mortgage off earlier but you won't drop the amount required to pay each month. Look at a mortgage amortization table to see this. This isn't because of the amortization table, it's because of the contract terms between you and the lender. After you make an extra principal payment, a new amortization schedule has to be calculated one way or another. It would be possible to re-calculate a new reduced monthly payment keeping the number of payments remaining fixed. Or you can calculate a new repayment schedule keeping the total monthly payment fixed and reducing the number of payments.  It happens the banks prefer to do the 2nd of these rather than the first, so that's the terms they offer when lending. Perhaps someone more knowledgeable can comment on why they prefer that.  In any case, by reducing your principal you improve your personal balance sheet and build equity in the mortgaged property so that, for example, if you sell you'll keep more of the proceeds and use less to pay off your loan.
