@Brent Coombs , thanks for your reply!
I think I didn't transmit my idea correctly. I am not boo-hooing about making more money and having to pay more tax. It would be like saying: "oh I don't want to make 200k a year in my job, I only want to make 100k so I pay less in taxes!"... that was truly not what I was saying...
What I am saying is, the more mature your mortgage gets, the more money you have tied down to a single property to get more or less the same yearly return out of that property. So your money is working less efficiently for you!
Let me use a real life example:
I just bought a townhouse for a $192k (value $200k) with $4k seller's assist for closing, with 25% down and 3.5% interest @15 yrs. Taxes are $3200 and insurance $400 (HOA takes care of external) and HOA 130$/month.
Mortgage $1030 (P&I)
T&I $300 ==
HOA $130 \
Total Expenses = $595
Managem. $83 /
Vac%Rep $165 ==
---------------------
Total $1625
Rent $1650 => Cash Flow = $25 (I even think this would be taxable, but I omitted that)
1st yr:
ROI: $7731 (Principal paid+cash flow)/$50k (down payment and omitted closing)= 15.462%
ROE: is the same as ROI in the first year as the down payment and equity should be the same in my opinion (unless you take into account the under market value at which you bought, the appreciation for 1 yr and don't omit closing costs, but it still doesn't change the concept; I omitted all of these things for simplicity).
2nd year
ROI: $7997/$50k = 15.994%
ROE: $7997/($7731(1st yr)+$7997(2nd yr)+$50k (down))= 12.167%
7th year
ROI: $9466/$50k = 18.932%
ROE: $9466/$107913 = 8.772%
12th year
ROI: $11216/$50k = 22.4332%
ROE: $11216/$162468 = 6.903%
16th year (1 yr after mortgage paid in full)
ROI: ($12660-$4304 due in income tax)/$50k = 16.712%
ROE: ($12660-$4304 due in income tax)/$200k = 4.178%
As per my example you can see that, once you are close to paying the mortgage off, your ROE is significantly lower than it was before. In the beginning 50-70k of equity were making me 7-10k a year, in the latter years 120k plus were making me about the same a year and when you pay it all off, now you have no mortgage to pay, so all the money after expenses is taxable as part of your income tax as far as I understand (I could be wrong), which in my case is already 34%.
So at the later years I am using a lot of money to make around 10k a year and after the mortgage is paid I am using all my equity to make even less, around 6k!! So this question is truly not about taxes, but about how to make my money work more and more efficiently for me. If I have to pay more taxes, so be it! as long as I am making more money, who cares?!
One idea I had was, always refinancing so you keep a debt of around 40-10% on each property, and then refinance again, so all your properties are working at max capacity and somewhat "controlled risk", as opposed to tying all that money down, for so little a year and then having to pay a third in taxes out of it.
I hope this helps illustrate what I am asking in a better way... I am sorry for the length, I don't know how else to express it, but with numbers.
Thanks!!
PD: also thanks for your advice... I own a house already, I am under agreement for a second one, and I have an offer put on a third one... I am getting full into this, doing the best I can with the best of my knowledge... I need to work on the deal part still, I think I am still not buying "under market enough"!
