I can probably cut windows on the back of the bedrooms and get some light in via windows from the porch/staircase...but not an ideal solution.This being a foreclosure the bank is not going to provide survey, so I am ordering survey.

I used what I learnt and bought my second house with a mortgage.In 2016, I bought an 8plex and 2 duplexes.( for 160k via commercial loan with no money down)Sorry for such a long first post.I thank you guys and gals so much!!

Have you bought or sold any properties via seller financing?

Some deals will fall in your lap...Patience...

I get back to Ca, did some investigating and found out that the property was sold via Quit Claim to another buyer and he did this while I was in town doing my walk through.

Raising outward cash flow, via added debt of any type, without raising income is an extremely dangerous play for somebody in their retirement years. 

You are correct, CAP rates are only for commercial properties, and this is a duplex meaning it is residential ... as such its fair market value will be determined via sold comparable properties.

The issue is even though the county taxes you that way, it has to be officially done via survey for the bank to proceed.

Feel free to send me more information via private message.
