I am getting 12% cap on this house in Kansas City that my partners totally rehabbed, great guys!

So I get the yield and cap gain distinction, and speaking only about the example at hand and not anything else, if the gain of $4k is realized within 30 days ($25k UPB and $21k discounted note purchase), plus the small one month of interest gain, the total return would be significant on that investment, and well worth spending the time to do it while also taking into consideration the efforts to reposition all the funds, both initial investment and total gain, correct?

Usually there are caps put in place for yearly increases to owner occupied houses, but not for investments.

Looking for 4-plex properties in the18-36% cap rate range.

Divide the net operating income by the average cap rate in the area to get your Max Purchase Price.

@Adam Gerig 7.5-8% CAP These are Brand New Houses or 5-8 years old.

Example a buyer says they want multifamily but want a B asset in a B area fully performing at a 10 cap ( not going to happen as they trade in the high 7's nationally and maybe hit the 8's if your lucky ).

Some lenders cap those at four, but they are available up to a total of 10 mortgaged properties.

If the hard money lender caps at $70,000. 

How about an app or a website that uses the API like padmapper.com that pulls sales price and the rent zestimate and automatically calculates a cap rate based on 50-60% of gross rents equal to a NOI?
