What return are you getting on your money from paying down a mortgage on a rental property?
"This is a great question, considering that all of your expenses including PITA, Maintenance, etc. are paid by a tenant, your cash flow is $0. Most people would stop and assume your investment is not performing and your only chance at making money is through appreciation. Your question eliminates appreciation so here are the returns you would get on your investment. The math will probably surprise many that you are actually earning a return on your money.   Annual Return = [((Future Value)/(Initial Investment))^((Periods per Year)/(Number of Periods) -1]*100 % 5.51% = [($200,000/$40,000)^(12/360)-1]*100 % As Chris Rea commented: The subtlety that some would miss is that while ""income covers expenses exactly"", embedded in the ""expenses"" is actually a repayment of the loan principal (and technically, that's not an ""expense"") so not all of the income is ""lost"" covering the ""expenses"". That repayment of principal portion of the rental income constitutes the return on the original capital invested." There are a few ways to look at this question. Assumptions. Per the original post's assumptions, this answer: In other words, if the owner paid the mortgage on its original schedule, the deal could boil down to a $ 40,000 up-front payment, in exchange for $ 200,000 of equity after 30 years.  Or the deal could boil down to a $ 40,000 up-front payment, in exchange for a $ 810.70 monthly payment starting in 30 years. While the owner is paying down the mortgage, the return on equity is the principal payment divided by the equity.  The principal payment is the net rent minus non-financing costs and interest, so it is actually a profit. The initial return on equity is 6.321 % APR, or 6.507 % APY.  This is calculated by dividing the $ 210.70 monthly principal payment by the initial $ 40,000 equity, and converting from monthly return to annual return. After 30 years, the return on equity is 4.864 % APR, or 4.974 % APY.  This is calculated by dividing the $ 810.70 monthly cash flow (which is no longer reduced by mortgage payments) by the $ 200,000 equity after 30 years, and converting from monthly return to annual return. The cap rate is the same as the return on equity in the absence of debt.  In this example, 4.864 % APR, or 4.974 % APY. The return on equity declines from 6.507 % APY initially to 4.974 % APY after 30 years. This is because the cap rate exceeds the note rate (4.974 % APY vs. 4.594 % APY), and the leverage decreases from 5x to 1x. The weighted average compound annual growth rate of the equity during the 30 years is 5.511 % APY.  Per the original poster's answer, this is computed by taking the 30th root of the 5-fold increase in equity.  Because the owner made no extra principal payments (besides those already discussed), the relevant amounts are the initial $ 40,000 owner payment and the final $ 200,000 owner equity.  5.511 % APY corresponds to a 5.377 % APR. The internal rate of return if the owner never sells can be computed by treating the deal as a $ 40,000 up-front payment, in exchange for an $ 810.70 monthly payment starting in 30 years.  The internal rate of return (IRR) is not a very useful number, because it assumes that you can somehow reinvest the eventual dividends at the same rate.  In this example, the IRR is 5.172 % APR, or 5.296  % APY.  In this example, the IRR is calculated by (iteratively) finding an interest rate for which (initial investment) * (1 + IRR) ^ (number periods before dividends start) = (periodic dividend) / (IRR - growth rate of dividend).  For example: $ 40,000 * (1.004309687)^360 = $ 810.70 / (0.004309687 - 0) = $ 188,111 I then converted the 0.431 % monthly IRR to an annual IRR. The deal can be thought of as a return on equity, plus a return on paying down the mortgage. When computing the return from paying down the mortgage, the initial equity is irrelevant.  It does not matter whether you start with a $ 160,000 mortgage on a $ 160,000 property, a $ 160,000 mortgage on a $ 200,000 property, or a $ 160,000 mortgage on a $ 1,000,000 property.  All that matters is the note rate on the mortgage, which is the applicable compound interest rate. The return on paying down the mortgage equals the note rate of the mortgage.  For a 4.5% note rate, this works out to a 4.594% annual percentage yield (APY). You can confirm this by looking at your amortization schedule.  Suppose you have a $ 160,000 mortgage with a fixed 4.5% APR note rate for 360 months.  Your monthly payment is $ 810.70.  In the first month, $ 600 goes toward interest, and $ 210.70 reduces the principal.  In other words, the $ 210.70 principal payment eliminated the need for a $ 810.70 payment 30 years later.  Notice that: . $ 210.70 * (1 + 0.045 / 12)^360 = $ 210.70 * (1.00375)^360 = $ 210.70 * 3.8477 = $ 810.71 which is within rounding error of $ 810.70. The interest rate is 3/8 % per month, which is an APR of 4.5%, and an APY of 4.594 %. As Chris pointed out: If your expenses are covered by the income exactly, as you have said to assume, then you are basically starting with a $40K asset (your starting equity), and ending with a $200K asset (a paid for home, at the same value since you have said to ignore any appreciation). So, to determine what you have earned on the $40K you leveraged 5x, wouldn't it be a matter of computing a CAGR that gets you from $40K to $200K in 30 years? The result would be a nominal return, not a real return. So, if I set up the problem correctly, it should be: $40,000 * (1 + Return)^30 = $200,000 Then solve for Return. It works out to be about 5.51% or so.
The answer depends entirely on your mortgage terms - is the interest rate low, how many years left? Questions like this are about Cost of Capital. If your mortgage has a low interest for a lot of years, you have a low cost of capital.  By paying it off early, you are dumping that low cost of capital. Use the extra money to start a business, invest in something or even buy another property (rental).  Whenever you have a low cost of capital, don't rush to get rid of it. Of course, if there are no other investment/business opportunities available and the extra money is going into a low return savings account, you might as well pay down your debt.  Or if you lack the self discipline to use the extra money properly - buying flat screens and meals out - then yeah just pay down your debt. But if you're disciplined with the extra money, use it to get access to more capital and make that new capital work for you. "I'm going to answer your questions out of order. Emergency fund: Depending on how conservative you are and how much insurance you have, you may want anywhere from 3-12 months of your expenses on hand. I like to keep 6 months worth liquid in a ""high-yield"" savings account. For your current expenses that would be $24k, but when this transaction completes, you will have a mortgage payment (which usually includes home-owners insurance and property taxes in addition to your other expenses) so a conservative guess might be an additional $3k/month, or a total of $42k for six months of expenses. So $40-$100k for an emergency fund depending on how conservative you are personally. Down payment: You should pay no less than 20% down ($150k) on a loan that size, particularly since you can afford it. My own philosophy is to pay as much as I can and pay the loan off as soon as possible, but there are valid reasons not to do that. If you can get a higher rate of return from that money invested elsewhere you may wish to keep a mortgage longer and invest the other money elsewhere. Mortgage term: A 15-year loan will generally get you the best interest rate available. If you paid $400k down, financing $350k at a 3.5% rate, your payment would be about $2500 on a 15-year loan. That doesn't include property taxes and home-owners insurance, but without knowing precisely where you live, I have no idea whether those would keep you inside the $3000 of additional monthly home expenses I mentioned above when discussing the emergency fund. That's how I would divide it up. I'd also pay more than the $2500 toward the mortgage if I could afford to, though I've always made that decision on a monthly basis when drawing up the budget for the next month." I am sorry to say, you are asking the wrong question. If I own a rental that I bought with cash, I have zero mortgage. The guy I sell it to uses a hard money lender (charging a high rate) and finances 100%. All of this means nothing to the prospective tenant.  In general, one would look at the rent to buy ratio in the area, and decide whether homes are selling for a price that makes it profitable to buy and then rent out.  In your situation, I understand you are looking to decide on a rent based on your costs. That ship has sailed. You own already. You need to look in the area and find out what your house will rent for. And that number will tell you whether you can afford to treat it as a rental or would be better off selling.  Keep in mind - you don't list a country, but if you are in US, part of a rental property is that you 'must' depreciate it each year. This is a tax thing. You reduce your cost basis each year and that amount is a loss against income from the rental or might be used against your ordinary income. But, when you sell, your basis is lower by this amount and you will be taxed on the difference from your basis to the sale price.  Edit: After reading OP's updated question, let me answer this way. There are experts who suggest that a rental property should have a high enough rent so that 50% of rent covers expenses. This doesn't include the mortgage. e.g. $1500 rent, $750 goes to taxes, insurance, maintenance, repairs, etc. the remaining $750 can be applied to the mortgage, and what remains is cash profit.  No one can give you more than a vague idea of what to look for, because you haven't shared the numbers. What are your taxes? Insurance? Annual costs for landscaping/snow plowing? Then take every item that has a limited life, and divide the cost by its lifetime. e.g. $12,000 roof over 20 years is $600. Do this for painting, and every appliance. Then allow a 10% vacancy rate. If you cover all of this and the mortgage, it may be worth keeping. Since you have zero equity, time is on your side, the price may rise, and hopefully, the monthly payments chip away at the loan. "I think the basic question you're asking is whether you'd be better off putting the $20K into an IRA or similar investment, or if your best bet is to pay down your mortgage.  The answer is...that depends. What you didn't share is what your mortgage balance is so that we can understand how using that money to pay down the mortgage would affect you.  The lower your remaining balance on the mortgage, the more impact paying it down will affect your long-term finances.  For example, if your remaining principal balance is more than $200k, paying down $20k in principal will not have as significant an effect as if you only have $100k principal balance and were paying down $20k of that. To me, one option is to put the $20k toward mortgage principal, then perhaps do a refinance on your remaining mortgage with the goal of getting a better interest rate.  This would double the benefit to you.  First, your mortgage payment would be lower by virtue of a lower principal balance (assuming you keep the same term period in your refinanced mortgage as you have now.  In other words, if you have a 15-year now, your new mortgage should be 15 years also to see the best effect on your payment).  Further, if you can obtain a lower interest rate on the new loan, now you have the dual benefit of a lower principal balance to pay down plus the reduced interest cost on that principal balance.  This would put money into your pocket immediately, which I think is part of your goal, although the question does hinge on what you'd pay in points and fees for a refinance. You can invest, but with that comes risk, and right now may not be the ideal time to enter the markets given all of the uncertainties with the ""Brexit"" issue.  By paying down your mortgage principal, even if you do nothing else, you can save yourself considerable interest in the long term which might be more beneficial than the return you'd get from the markets or an IRA at this point. I hope this helps. Good luck!" how much taxes would I pay on my income from the rent they would pay me? The same as on any other income. California doesn't have any special taxes for rental/passive income. Bothe CA and the Federal tax laws do have special treatment, but it is for losses from rental. Income is considered unearned regular income and is taxed at regular brackets. Would I be able to deduct the cost of the mortgage from the rental income? The cost of mortgage, yes. I.e.: the interest you pay. Similarly you can deduct any other expense needed to maintain the property. This is assuming you're renting it out at FMV. If not, would I pay the ordinary income tax on that income? In particular, would I pay CA income tax on it, even though the property would be in WA? Yes. Don't know how WA taxes rental income, but since you are a California tax resident - you will definitely be taxed by California on this, as part of your worldwide income. I would go with the 2nd option (put down as little as possible) with a small caveat: avoid the mortgage insurance if you can and put down 20%. Holding your rental property(ies)'s mortgage has some benefits: You can write off the mortgage interest.  In Canada you cannot write off the mortgage interest from your primary residence. You can write off stuff renovations and new appliances.  You can use this to your advantage if you have both a primary residence and a rental property.  Get my drift? P.S. I do not think it's a good time right now to buy a property and rent it out simply because the housing prices are over-priced.  The rate of return of your investment is too low. P.S.2.  I get the feeling from your question that you would like to purchase several properties in the long-term future.  I would like to say that the key to good and low risk investing is diversification.  Don't put all of your money into one basket.  This includes real estate.  Like any other investment, real estate goes down too.  In the last 50 or so years real estate has only apprepriated around 2.5% per year.  While, real estate is a good long term investment, don't make it 80% of your investment portfolio. Even after the real estate crash, there are banks that lend money outside of the rules I'll share.  A fully qualified mortgage is typically run at debt to income ratios of 28/36, where 28% of your gross monthly income can apply to the mortgage, property tax, and insurance, and the 36% is the total monthly debt (including the mortgage, etc) plus car loan student loan, etc. It's less about the total loan on the potential than about these ratios. The bank may allow for 75% of monthly rent so until rentals are running at a profit, they may seem a loss, even while just breaking even.  This is just an overview, each bank may vary a bit. yes.   you can take out 500,000 form your paid of house.  you pay back 500,000 at 3.5. percent.       you do get a tax break for not owning your house.  it is less then 3.5 you are paying back the back. about one forth of that, BUT you take the 500,000 in invest.   Now cd low 1 percent,  stock is risky.    You can do REIT, with are about 8 to 12  every year. so even at 8 - tax 1.5 is 6.5 - 3.5 bank loan.  that   3 percent on your 500,000 thousand, plus tax break, but that only at 8 percent.      or 500,000 and buy a apartment building, again about 7 to 10 percent,   so that 2 to 3 percent profit, but the building goes up over years.
