That affects your loan amount and then principal & interest payment.2) Estimate rents based on recent rental comps3) Account for all operating expenses such as property taxes, insurance, repairs & maintenance (landscaping, snow removal, cleaning etc), property management (if applicable), vacancy, utilities (what does the tenant pay vs what you would pay?)

If you get a loan it must be non-recourse and will require about 30-50% down.

The apartment sale price 275k, loan amount 261k with 19k grant, no money out of pocket. after rehab rent 1850-2k month for location. my home 4 bd 2.5 b worth 217-230k will rent for 1800-2k month.

Of course, I had to make additional assumptions about the cost of property taxes, insurance etc. 

Ask your loan officer if you qualify. 

How do you pay for the tax and insurance?

My wife nothing but student loans and car debt.

I am researching VA OTC loans in Southern California (Los Angeles County).
