Can extra mortgage payments be made to lower the monthly payment amount?
Some types of loans allow for reamortization (recasting) - which does exactly what you're talking about (making a big payment and then refiguring the monthly amount rather than the overall lifespan), without requiring any kind of a fee that refinancing does. Not every, or even most, mortgages, allow for recasting. And most that do offer recasting, may limit the recasting to a once-a-loan type of thing. So check beforehand, and make those big payments before you do any recasting. (Most banks and mortgage servicing companies may not advertise or even speak about recasting options unless you specifically ask your loan officer.) That's tricky. Typically you lock in the minimum monthly payment when you close the loan. You can pay more but not less. Options: Typically, this is not an option, as the monthly payments are fixed. It depends on the willingness of your financing bank for such a change. You probably will have to refinance (with them or another lender); which is not a bad thing, as you even can get a lower interest rate potentially (as of Jan 2017 - this will change). Consider too: It could be a better solution to instead invest the 25000, and use the investment returns to fill up the difference every month. Certainly more effort, but you probably come out ahead financially.
Because a paying down a liability and thus gaining asset equity is not technically an expense, GnuCash will not include it in any expense reports. However, you can abuse the system a bit to do what you want.  The mortgage payment should be divided into principle, interest, and escrow / tax / insurance accounts. For example: A mortgage payment will then be a split transaction that puts money into these accounts from your bank account: For completeness, the escrow account will periodically be used to pay actual expenses, which just moves the expense from escrow into insurance or tax. This is nice so that expenses for a month aren't inflated due to a tax payment being made: Now, this is all fairly typical and results in all but the principle part of the mortgage payment being included in expense reports. The trick then is to duplicate the principle portion in a way that it makes its way into your expenses. One way to do this is to create a principle expense account and also a fictional equity account that provides the funds to pay it: Every time you record a mortgage payment, add a transfer from this equity account into the Principle Payments expense account. This will mess things up at some level, since you're inventing an expense that does not truly exist, but if you're using GnuCash more to monitor monthly cash flow, it causes the Income/Expense report to finally make sense. Example transaction split: "@fredsbend, Hope this helps!  ""I understand that a reverse mortgage can be paid out in two ways: A lump sum and monthly payments. I figure that if you take the lump sum, eventually, the bank wants you to start paying it back."" Answer:   Actually, there are 3 payout options, or 4 if you consider a combination payout as another one. There's a lump sum, a line of credit, or the monthly payout, or a combination.  ""I figure that if you take the monthly payments, eventually, the bank stops paying out and wants you to pay it back. In both situations, interest accrues and this is how the bank makes money off of the deal"".  Answer: The only time the monthly payments would stop would be if the borrower defaults on the lenders' terms or they no longer live at home. You are right though, and interest does accrue on whichever payment is decided on. I'm not sure how the lender makes money, probably by the interest, but I know borrowers are protected against high rates and owing more than your house. Here's an article I found that goes over the protections more in detail: https://www.americanadvisorsgroup.com/news/6-consumer-protections-reverse-mortgage-loan-borrowers.  ""But what determines when you have to begin paying back the reverse mortgage? Some sources online seem to say that it's based only on if you die or would like to sell/move. That can't be right in all situations, because you could end up with a massive debt on a property more than its value.""  Answer: There are a lot of protections or regulations in place to protect anyone who takes out a reverse mortgage. One being, you can't owe MORE than your house is valued at during the time of repayment, a reverse mortgage is a non-recourse loan. In the instance that your house is less than you owe, you either sell the home and the proceeds are used to pay the loan and you keep the rest OR if you owe more than the house proceeds of the home go to the lender. Either way, you're not left paying for a ""mortgage"" without the house. In the case the parent, grandparent passes, then the heirs would have a choice of either paying back the reverse mortgage in payments, OR they can sell the house, heirs are protected during this as well to make sure they're not left with major debt in case of anything.  Is there a formula to figure out when the bank stops the monthly payments and then wants it back?  **Answer:**The amount becomes due if loan terms are not met, but the lender will discuss the options if it comes to that.  Is there a different formula for when the lump sum would have to be paid back?""  Answer: Each payout option has the same terms and the same pay back terms. As long as terms are met, the lender can't ask for early repayment." The formula for determining the number of payments (months) you'll need to make on your loan is:  where i=monthly interest rate (annual rate / 12), A=loan amount (principal), and P=monthly payment. To determine the total interest that you will pay, you can use the following formula:  where P=monthly payment, N=number of payments (from above formula), and A=loan amount (principal). A quick example: using the numbers in the screenshot above ($10,000 loan, $500 monthly payment, 10% APR), the number of payments ends up to be 21.97 (which means that payment number 22 is slightly less than the rest).  In the second formula, you take that number times your $500 payment and determine that you have paid $10,984.81 over the course of the entire loan period.  Subtracting the principal, you have paid $984.81 in total interest. On your spreadsheet, the function you are looking for is NPER: NPER(rate, payment_amount, present_value, [future_value, end_or_beginning]) rate - The interest rate. (This should be the monthly rate, or the annual rate divided by 12.) payment_amount - The amount of each payment made. (For a loan payment, this should be a negative number.) present_value - The current value of the annuity. (The initial principal of the loan) future_value - [ OPTIONAL ] - The future value remaining after the final payment has been made.  (This should be 0, the default if omitted.) end_or_beginning - [ OPTIONAL - 0 by default ] - Whether payments are due at the end (0) or beginning (1) of each period. You should have drafted a contract of purchase that stipulated out equity stake in the home based of his down payment and yours, along with future monthly payments.  But morally, if the house sells, yielding 100,000 profit (after fees/taxes/etc), you should get ( To Calculate Your Cut: (20,000 + Your Total Mortgage Payments Applied to Principle) / (1,900 + His Total Mortgage Payments Applied to Principle Only) * Profit on Sale of House After All Fees = Your Cut His would be: (1,900 + His Total Mortgage Payments Applied to Principle Only) / (20,000 + Your Total Mortgage Payments Applied to Principle) * Profit on Sale of House After All Fees = His Cut You'd then take mortgage payment totals for each; and calculate the payments made towards interest; and claim the correct amount each of you paid on payments for the mortgage interest deduction when you file your taxes. Although, depending on how the loan is written, the banks may issue 1099s which dont reflect actual payments made... Talk to an accountant. I found this article to clarify some of the issues. One point raised is that the concession can be thought of as getting tax exemption for the closing costs, which normally are not allow. I'm not sure I follow this logic, since you can only deduct the interest, not the principal. I asked a lender, and he verified you can only spend the concession money on closing costs. I think if your closing costs are less than 1% of the loan, its probably not worth it to go for a concession over the price reduction. With interest rates so low, its also not cost effective to buy down points on the loan. This should limit most of your closing costs. "Your first question has been answered quite well already. To answer your second question: ""If you pay extra, do you want the extra to go toward the interest or   toward the principal?"" This gives the consumer some flexibility to decide how additional payments are applied. It might seem like a no-brainer to always apply extra payments towards principal - that way, the interest amounts on future payments will be lower and (if you're billed a fixed amount each month) more of each regular payment will then be applied to principal, shortening the term of the loan. However, while it would mean spending more over the life of the loan, there are certain advantages to applying extra payments towards interest†. The main advantage is that it pays your account ahead and means you don't have to make another payment as soon. You could use this strategy to give yourself a buffer of several months, so that if you should ever run into financial hardship you can stop making mortgage payments for a while without the risk of foreclosure. † Note, in most cases it's more likely that you are simply paying more without specifying to the lender that it should be used as principal curtailment. I haven't seen cases where you can explicitly ask the extra to be ""applied toward interest"". In this situation the funds would be held until you've provided enough to cover one or more monthly payments in full, at which point your ""next payment due"" date will simply be extended.  Another advantage is that the funds that are being held (not due yet, not allocated toward any specific payment, maybe held in escrow) may be refundable to you, upon request. This would depend on the lender's policy. Some will permit refunds of credit balances that go beyond what is necessary to cover the current month's bill. Whether you apply extra payments towards principal or not, it makes little difference to the bank. Any additional payments received increase their immediate cash flow. The cash can be reinvested immediately by them into whatever they are currently focusing on." "There is no guarantee improvements will raise the appraised value.  You also don't want your property tax appraisal to go up if you can avoid it. Since you are talking on the order of $10k I'll assume you're only a few thousand dollars more from getting to 20%. That said, any schemes you might come up with like refinancing or second line of credit will probably cost more in fees than they are worth, unless you can get a much nicer interest rate. Figure out how long you plan to stay there, Evaluate your options (do nothing, principal reduction, refinance for 30, 15, or even an ARM) and figure out your bottom line by comparing everything in a spreadsheet One more thing: if you do pay a substantial amount of extra principal, you can ask the lender to ""rebalance"" which will correct the minimum monthly payment to your remaining term. This will likely incur a fee, but could be helpful in an emergency" You can often convert the outstanding balance of a HELOC into a fixed-rate home equity loan, generally with the same bank.  Doing this can open possibilities to extend the term allowing for lower monthly payments, but resulting in a larger overall payoff cost. Most HELOCs allow for an interest-only payment or in some cases no-payment at all if you still have unused available credit. Not advising that you do this. If you are struggling with the size of the payment converting to a fixed-rate, fixed-term loan may be what you need. The key will be getting the term such that you can manage both the principal and interest that will be included in the payment.
