I'm thinking I could buy the containers for $20-30k (7-10 containers total), land for about the same, maybe more.

When did i have to check this thing's outAnd what are the steps that i missed with a total rehab property what are the pitfalls? 

It needed all new flooring, windows, painting, HVAC and appliances but I was able to turn it around in about 2 months and get it rented for 775 and 700 for a total monthly rent of 1475.   

Hi,I have 50K extra to invest, and I have already diversified my other investments to many different areas using: Vanguard 3-fund index fund portfolio ( vtsax, vtiax, vwitx (60/30/10) ), M1Finance 3-fund ETF portfolio ( vti, vxus, vteb (60/30/10), individual company stocks and ESPP (around 80K), Treasury notes (6-month and 1-year, total of 40K), I-bonds (10K limit for this year), some CDs (1-year 2% at ally and synchrony), and some in savings account in synchrony.How can i invest the extra 50K?

That is totally my thinking as well.

@Griffin MyersLenders use a few calculations in determining how much you can afford.In general, they look at your total income and debts and FICO.

Great observation and totally agree. 

You could make an amortization table in excel and show them the total amount of interest they could make on top of the sales price by seller financing.

My favorites are: The Millionaire MindRich Dad Poor Dadand Think and Grow RichI also love Dave Ramsey’s total money makeover for personal finance and bad debt reduction.

HUD 4155.1 5.b.7 (opens in .pdf) reads:The borrower may obtain a loan for the total required investment, as long as satisfactory evidence is provided that the loan is fully secured by assets such as investment accounts or real property.
