I put a small downpayment in and took a private loan (for the 25% ownership) from them that I'm paying back w/ interest and somehow we structured it to count as income for them produced by this same property...

In rent it produces 3,000 dollars a month. 

If we use $10K invested per property (20% of the lower of the OP price range) and a 10% S&P return (approximate lifetime rate of return of the S&P) would produce by $60K. 

The house is somewhat more likely to sell at auction now, since by auction time it will be a good-looking,  income-producing rental asset with stable tenants rather than an vermin-infested trash heap occupied by unstable addicts. 

Looking at LP+Promote level performance indicators might be an interesting exercise, but it doesn't produce much value to me because I'm not doing it to compare one investment option versus another, I'd be doing it just to see how high my IRR or multiple is. 

That's why rental properties make a great business, you don't need to stop doing your other income producing activities to get started.

I'm currently thinking about going to work for a builder... still not my dream but it produces income.

Rarely are a history of rent deposits ever produced in a single family deal. 

$50k loans are tough, they are so tiny, most of the bankers won’t touch them so that leaves you with few options .... that’s the downside of small loans, no medium-top producers will take them, that leaves you with begginers or opportunists ... 

Neither of our businesses produces much income after deduction of expenses.
