I feel pretty confident about dealing with numbers and looking for a solution from all angles.

I know there are angles I'm not thinking of, or am not even aware of and I'd love to hear why this plan will fail, or what needs to be changed to give a better chance of success.I appreciate any and all feedback and sorry if I'm slow to respond. 

there is a wide range in that area, some spots can get in the 900 to 1000 range other streets you are lucky if you get 700.  

The amount will depend on a wide variety of factors.

Buy double wide with 1 acre to 2 of land for $25k, 5-10k fix up and rent for 12 months (must do this step for tax reasons) then seller finance 3 per year per myself and per my wife to stay within Dodd Frank guidelines.  

More knowledge, more money, more confident, more BP contacts, more questions, more effort, and more answers to and from the BP family, more planning, more executions on your plans along with eyes wide open.

This happens for a wide variety of reason (zoning, violations, defunct..).Then run the numbers.

In California you do not need to be licensed to manage your own properties, but I strongly recommend purchasing a landlord law book as the laws can be tricky here and they can vary widely by county and city.

I peeled away the tile in the next room, and it covered a 2' square of plywood covering an access hole to what looks like an old brick septic system that's probably 5' deep, 5' wide, and 8' long (I didn't climb down in to measure it).

I will review that angle as well.Dave NA thanks for your insight as well.
