I will explore the JV approach.

Keep it short and respectful of their time, and offer to meet in person if they’re open to it.Join Tacoma-specific Facebook groups.

Cosmo - I personally don't know Phoenix well, but if I had to do this in another city I would look at income levels, crime levels, and population growth (if you can) by zip code and/or area within a DMA as a starting point.

The person I would seek advice from is a CPA about this. 

Imagine making millions of dollars over the course of your career and then having to pay 30-50% every year to uncle sam instead of compounding that cash over time.This is exactly what real estate professionals have learned to mitigate.To reduce their taxable income, they just buy a building every year, do a cost seg, and use depreciation to reduce their tax liability dramatically.Their personal wealth snowball grows much larger and much faster than their W2 counterparts who give most of their money back to the government each year.Following this strategy as a real estate professional is one of best ways to end up with a much larger net worth at the end of your career.

I used $80k to pay off personal debts and $50k to remodel it by myself with my two hands.

Was that person me or another person as that sounds like something I have been telling people? 

If I understand correctly; the seller would receive 80% ($40,000) directly from the mortgagee at closing and would enter into a personal agreement with me for the 20% down payment ($10,000) in which he would be reimbursed separately from my mortgage payments at a separately agreed upon rate and term?

I have no idea who I should reach out to for help, and I just do not understand how this person no longer responds to emails or returns phone calls.I hope someone can provide some guidance. 

Hey @Anthony Sigala many folks might be optimistic about this rule but the "rule" was created during a very specific and particular time in real estate as a way to help newer investors have a framework on how to approach rental properties without going in blind.
