Pay off entire mortgage or put into investments
I like this option, rather than exposing all 600k to market risk, I'd think of paying off the mortgage as a way to diversify my portfolio. Expose 400k to market risk, and get a guaranteed 3.75% return on that 200k (in essence). Then you can invest the money you were putting towards your mortgage each month.  The potential disadvantage, is that the extra 200k investment could earn significantly more than 3.75%, and you'd lose out on some money. Historically, the market beats 3.75%, and you'd come out ahead investing everything. There's no guarantee. You also don't have to keep your money invested, you can change your position down the road and pay off the house. I feel best about a paid off house, but I know that my sense of security carries opportunity cost. Up to you to decide how much risk you're willing to accept. Also, if you don't have an emergency fund, I'd set up that first and then go from there with investing/paying off house. At the moment the interest rate... implies a variable rate mortgage.  I believe rates are only going to go up from here. So, if I were in your position, I would pay off the mortgage first.  If you don't have 3-6 months in savings for an emergency, I would invest that much money in low risk investments.  Anything remaining I would invest in a balanced portfolio of mutual funds. The biggest benefit to this is the flexibility it gives you.  Not being burdened by a monthly mortgage frees you up to invest.  This may be in your stock portfolio each month or it may be in your community or charitable causes. You have financial margin. At the area where I live (Finland), banks typically charge a lot more for additional mortgage credit taken after purchasing the house. So, if you are planning to purchase a house, and pay it with a mortgage, you get a very good rate, but if you pay back the mortgage and then realize you need additional credit, you get a much worse rate. So, if this is applicable to your area as well, I would simply buy stocks after you have paid enough of the mortgage that it is only 50% of the house price or so. This is especially good advice if you are young. Also, if your mortgage is a fixed rate and not an adjustable rate mortgage, you probably have a very low permanent interest rate on it as interest rates are low currently (adjustable rate mortgages will also have a low rate but it will surely go up). Some people say there's a bubble currently in the stock market, but actually the bubble is in the bond market. Stocks are expensive because the other alternatives (bonds) are expensive as well. Paying back your mortgage is equivalent to investing money in bonds. I don't invest in bonds at the current ridiculously low interest rates; I merely invest in stocks and have a small cash reserve that will become even smaller as I discover new investment opportunities. I could pay back a significant percentage (about 50%) of the loans I have by selling my stocks and using my cash reserves. I don't do that; I invest in stocks instead, and am planning to increase my exposure to the stock market at a healthy pace. Also, consider the fact that mortgage is cheap credit. If you need additional credit for consumption due to e.g. becoming suddenly unemployed, you will get it only at very expensive rates, if at all. If you're very near the retirement age (I'm not), this advice may not be applicable to you. Edit: and oh, if your mortgage is fixed rate, and interest rates have come down, the bank will require you to pay the opportunity cost of the unpaid interests. So, you may need to pay more than you owe the bank. Edit2: let's assume the bank offered you a 4% fixed rate for a 10-year loan, which you agreed to. Now let's also assume interest rates of new agreements have come down to 2%. It would be a loss to the bank to pay back the amount of the loan (because the bank cannot get 4% by offering somebody else a new loan, only 2%), unless you paid also 10 years * (4% - 2%) * amount = 20% * amount of lost interest income. At least where I live, in fixed rate loans, one needs to pay back the bank this opportunity cost of unpaid interests.
As mentioned, the main advantage of a 15-year loan compared to a 30-year loan is that the 15-year loan should come at a discounted rate.  All things equal, the main advantage of the 30-year loan is that the payment is lower. A completely different argument from what you are hearing is that if you can get a low interest rate, you should get the longest loan possible.  It seem unlikely that interest rates are going to get much lower than they are and it's far more likely that they will get higher.  In 15 years, if interest rates are back up around 6% or more (where they were when I bought my first home) and you are 15 years into a 30 year mortgage, you'll being enjoying an interest rate that no one can get. You need to keep in mind that as the loan is paid off, you will earn exactly 0% on the principal you've paid.  If for some reason the value of the home drops, you lose that portion of the principal.  The only way you can get access to that capital is to sell the house.  You (generally) can't sell part of the house to send a kid to college.  You can take out another mortgage but it is going to be at the current going rate which is likely higher than current rates. Another thing to consider that over the course of 30 years, inflation is going to make a fixed payment cheaper over time.  Let's say you make $60K and you have a monthly payment of $1000 or 20% of your annual income.  In 15 years at a 1% annualized wage growth rate, it will be 17% of your income.  If you get a few raises or inflation jumps up, it will be a lot more than that.  For example, at a 2% annualized growth rate, it's only 15% of your income after 15 years. In places where long-term fixed rates are not available, shorter mortgages are common because of the risk of higher rates later.  It's also more common to pay them off early for the same reason.   Taking on a higher payment to pay off the loan early only really only helps you if you can get through the entire payment and 15 years is still a long way off.  Then if you lose your job then, you only have to worry about taxes and upkeep but that means you can still lose the home.  If you instead take the extra money and keep a rainy day fund, you'll have access to that money if you hit a rough patch.  If you put all of your extra cash in the house, you'll be forced to sell if you need that capital and it may not be at the best time.  You might not even be able to pay off the loan at the current market value. My father took out a 30 year loan and followed the advice of an older coworker to 'buy as much house as possible because inflation will pay for it'.  By the end of the loan, he was paying something like $250 a month and the house was worth upwards of $200K.  That is, his mortgage payment was less than the payment on a cheap car.  It was an insignificant cost compared to his income and he had been able to invest enough to retire in comfort.  Of course when he bought it, inflation was above 10% so it's bit different today but the same concepts still apply, just different numbers.  I personally would not take anything less than a 30 year loan at current rates unless I planned to retire in 15 years. "Math says invest in the Market (But paying off your mortgage early is a valid option if you are very risk averse.) You are going to get a better return by investing in the stock market.  In the US in 2015/2016, mortgages are 3%-4%, and give you a tax break.  The rate of return on the stock market is ~10%, (closer to 6% after you subtract out inflation, taxes, fees, etc.) Since 10 > 3, (or 6% > 4%, to use the pessimistic numbers)  investing in the market is the better deal. But... The market has risk, and your mortgage does not.  If you are very risk averse paying off the mortgage may make sense. As an example:  Family A has a single ""breadwinner"", who works a low skilled job. Family B has 2 working spouses, both in high skill white collar positions.   These two families are going to have wildly different risk tolerances.  It may make sense for family A to ""invest"" its extra money in paying off the mortgage, after they have tackled high interest debt, built an emergency fund, maxed the 401k, etc. Personally I would not: in the US you cannot recoup pre-payments if you lose your job.  If I was very risk averse, I would keep my extra money as cash, so I could pay my mortgage after I lost my job.  It is never going to make sense for family B to pay the mortgage early.  At that point, any decision to pre-pay is going to be based on emotion and not logic." Should I use the money to pay off student loans and future grad expenses for me? Yes.  The main drawback to student loans is that they cannot be gotten rid of except by paying them off (other than extreme circumstances such as death or complete disability).  A mortgage, car loan, or other collateralized loans can be dealt with by selling the underlying collateral.  Credit card loans can be discharged in bankruptcy. Stop borrowing for college, pay for it in cash, then decide what to do with the rest. Make sure you have a comfortable amount saved for emergencies in a completely liquid account (not a retirement account or CDs), and continue to pay off with the rest.  You might also consider putting some away for your kids' college, so  I want to get my older son into a private middle school for 2 years. They have a hardy endowment and may offer us a decent need based scholarship if we look worthy on paper I have a hard time getting behind this plan with a 238K mortgage.  If you want to apply for scholarships that's great - but don't finagle your finances to look like you're poor when you have a quarter-million-dollar house.  If you want to save some for private school then do that out of what you have.  Otherwise either rearrange your priorities so you can afford it or private school might not be in the cards for you. That said- while it was a blessing to be able to pay off the second mortgage and credit cards, your hesitancy to pay off the student loans makes me wonder if you will start living within your means after the loans are paid off.  My concern is that your current spending levels that got you in this much debt in the first place will put you back in debt in the near future, and you won't have another inheritance to help pull you out. I know that wasn't your question, but I felt like I needed to add that to my answer as well. Rules of thumb? Sure - Put down 20% to pay no PMI.  The mortgage payment (including property tax) should be no more than 28% of your gross monthly income.  These two rules will certainly put a cap on the home price. If you have more than the 20% to put down on the house you like, stop right here. Don't put more down and don't buy a bigger house. Set that money aside for long term investing (i.e. retirement savings) or your emergency fund. You can always make extra payments and shorten the length of the mortgage, you just can't easily get it back.  In my opinion, one is better off getting a home that's too small and paying the transaction costs to upsize 5-10 years later than to buy too big, and pay all the costs associated with the home for the time you are living there. The mortgage, property tax, maintenance, etc. The too-big house can really take it toll on your wallet. Congratulations on doing all the right things in your financial life. To me, the answer to your question is a no-brainer: pay off the loans immediately. However, I am sure that some people will post answers arguing exactly the opposite. I would also  recommend using the extra cash that you will have each month (since the payments on the loans will disappear) to increase your 401k contributions even though they will not attract additional company match, and once again, you will certainly get answers telling you why doing so is a very bad idea. This is a case where human nature and arithmetic lead to different results. Depending on the your income, the effective interest rate on the mortgage is probably right around 2.5%.  So purely by arithmetic, the absolute cheapest way to go is to put the $11k to the bigger car loan, then pay off the mortgage, then the smaller car loan. The Debt Snowball is more effective however, because it works better for people. Progress is demonstrated quickly, which maintains (and often enhances) motivation to continue.  I can say as a case in point, having tried both methods, that if does indeed work.  So, I am with you ... pay off the car loan first, and roll that payment into the bigger car loan. If you add no extra dollars, you should get the small loan paid off in 6 to 8 months and the bigger car loan in another 16 to 18 months. It sounds like from your message that you have another $1500 or so a month.  If that is the case ... small loan paid off in two months, bigger loan paid off in another year.  If you stick with the Ramsay program, you then build an emergency fund and start investing. Good luck! "Is the mortgage debt too high? The rental property is in a hot RE market, so could be easily sold with significant equity. However, they would prefer to keep it. Given the current income, there is no stress. However in absence of any other liquid [cash/near cash] assets, having everything locked into Mortgage is quite high. Even if real estate builds assets, these are highly illiquid investments. Have debt on such investments is risky; if there are no other investments. Essentially everything looks fine now, but if there is an crisis, unwinding mortgage debt is time consuming and if it forces distress sale, it would wipe out any gains. Can they afford another mortgage, and in what amount? (e.g. they are considering $50K for a small cabin, which could be rented out). I guess they can. But should they? Or diversify into other assets like stocks etc. Other than setting cash aside, what would be some good uses of funds to make sure the money would appreciate and outpace inflation and add a nice bonus to retirement? Mutual Funds / Stocks / bullions / 401K or other such retirement plans. They are currently in mid-30's. If there is ONE key strategy or decision they could make today that would help them retire ""early"" (say, mid-50's), what should it be? This opinion based ... it depends on ""what their lifestyle is"" and what would they want their ""lifestyle"" to be when they retire. They should look at saving enough corpus that would give an year on year yield equivalent to the retirement expenses." "I agree with @Pete that you may be well-advised to pay off your loans first and go from there.  Even though you may not be ""required"" to make payments on your own loan based on your income, that debt will play a large factor in your borrowing ability until it is gone, which hinders your ability to move toward home ownership.   If you are in a fortunate enough position to totally pay off both your loan and hers from cash on hand then you should.  It would still leave you with more than $112,000 and no debt, which is a big priority and advantage for a young couple. Mind you, this doesn't keep you from starting an investment plan with some portion of the remaining funds (the advice to keep six months' income in the bank is very wise) through perhaps a mutual fund if you don't want to directly manage the investments yourself.  The advantage of mutual funds is the ability to choose the level of risk you're willing to take and let professionals manage how to achieve your goals for you.  You can always make adjustments to your funds as your circumstances change. Again, I'd emphasize ridding yourself of the student loan debt as the first move, then looking at how to invest the remainder."
