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. 

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.

A dwelling unit is not habitable if it violates provisions of housing or health codes concerning the health, safety, sanitation or fitness for habitation of the dwelling unit or if it substantially lacks:(a) Effective waterproofing and weather protection of the roof and exterior walls, including windows and doors.

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.

Be aware of the title chain and insurances.
