And there is less to maintain, and cost to get in is generally cheaper.The downside, is the HOA fees will eat a lot of cash flow, the turn over is higher I've found as they would rather live in a house than a complex.

Not $2,700 worth of difficult for sure and I could do it in 2 days max including assembly of the cabinets.Had a bid for $800 to tear down the top 2/3 of the brick facade; took us 1 1/2 hours with a hammer drill.Bottom line, hiring contractors would probably eat away about $20k in profit if I hired them vs DIY. 

And then beside that, does it even make sense alot of the time to buy such small properties if you can't manage them yourself - do the management fees eat up most of your cash flow? 

Second, rather than putting all of your entire nest egg into a single property, where you would be exposed to significant single property risk from lack of diversification, you can spread your money over many properties, with minimums for accredited offerings typically around $5000 to $10,000.

Most note buyers will expect a discount on your note, which will eat into your profits.

You have to decide if you want all of your eggs in one basket- no one can tell you what's "best" for you.

That one was full of termites and you had to walk away, termites are eating and you're making more offers.

Realistically one vacant unit per year could eat up $3000 in paint, carpet and other upgrades.

The legal and accounting fees alone would eat you up.

And ensure you have a little nest egg on the side in case of any repair/maintenance issues as something always comes up.
