So in my opinion, it is a very slim strategy, because if your refi doesn't work, there is not that much meat on the bone for too many optional strategies. also, re-check you rental rates in that neighbor (pre AND post renovations) hope this helps. 

The numbers on your deal are a bit slim, although there is probably some upside in those rent.

The margins are slim and it is all a volume game.

Further, owners probably don't want to sell to someone who is only putting 3% down payment as they know the likelihood of closing is slim.

Learn the trade, and see if it suits you.Just soemthing to think about:Truth: I think we can agree that a professsional athlete makes lots of moneyReality: chances of any of us being a professional athlete is pretty slim...You never really want to put anybody “down” before they’ve tried it (not to mention I’ve never met you, regardless of whether I’m a good job of character or sales potential).

I've invested in a small town and there are slim PM pickings here.

Owner financing is an option(slim option though).

I took the 40-hour course and got certified to do lead abatement about 15 years ago and never was interested in getting involved with lead abatement.Lead is also found in older bathtubs when lead was put in the glazing and in ceramic tile.Personally, I think lead is more dangerous than asbestos because lead causes very serious mental issues for children children where they really do become mentally handicapped vs. the b.s. about mold and even when asbestos is present in a rental unit, or commercial building the chances that the asbestos is loose enough to circulate through the air is slim to none, but there are some rare claims.

I agree, cash flow is slim and I avoid presuming appreciation will make up for it.  

The chances of something happening to all 20 units at the same time is extremely slim.
