Nearly everything frankly - payroll, R&M, insurance, G&A.

Here is an example: SFH property listed for 135k that need little rehab it is on Embarcadero  Houston, TX 77082. it is 1800sf 3 BR and 1.5 bathrooms. the numbers are:P and I 562 (based on 30 years loan and interest rate 4.5)HOA 14Taxes 314 insurance 90so this come to $980 and not taking into consideration PM, vacancies, CAPeX, flood insurance. 

I took note of these properties and spoke with a few home owners about the houses and many say that the houses has been vacant for years.. 

Brian Kraft I think what you have to start with is variables that you know: what they rent out for today, property taxes, vacancy for the area, insurance, PM fees, etc.

I got lucky and met with the home owner that lives across the street.

You could do that or buy a 1 to 4 unit home and get a "house hacking" loan that is insured and only requires 3 1/2% down payment and usually about one year minimum move in/occupancy in 1 of the units. 

The downside for you is perhaps some things will be more expensive like insurance is a little higher but again nothing astronomical.

In it is a section on Indemnification insurance, 20.B for those of you that have it.

I let my contractor registration and insurance expire this year because I have nothing planned in the city proper for a few years.

At the very least, I'd like to try and match up my mortagage/hoa fees/insurance/tax to what I can rent it for.
