I'm actually interesting in buying performing notes and enjoying the cash flow to minimize risk.

Very minimal repairs.

This is a minimal cost to make sure you're spending your money wisely.

But I don't see why @Bobby Holley should settle for just $5k on the deal merely because he was clever enough to have minimal dollars into it.If I had $25k lying around only earning bank Interest Rates (or even if I could borrow it at conventional Interest Rate), I might be persuaded to lend it to a friend that I trusted for $5k interest over $3 months!

I am exploring the options and the following interests me most:- Tax Overages and Tax Liens for minimal starting investment and to get in the action,- Occasional rehabs for relatively quick capital building (and because I love it!!!)

While my goals aren't quite as lofty (yet), I've got a couple of buy and hold properties now and am on the hunt for some minimally invasive flips.

If you live in a city that has a small amount of multi-family properties in general, and a very minimal amount of multi-family properties that are not in high-crime areas:Generally speaking, would it be better to invest in a quadriplex that cash flows $300 after all expenses or would it be better to invest in a single family property that cash flows $150 (assuming that the location was the same)?

Buy  with cash for immediate closing and refi later to recoup cash for the next deal.If you want to maximize cashflow with profits, minimize debt to reap profits.  

All of our renters sign long term, 6-month leases and we have minimal turn-over...our average stay is now 18 months.  

All the same laundry and kid space there may be minimal costs for the return.
