I appreciate the Wall Street Journal's study. 

My current goal is to buy and hold two properties- either a single family, duplex or townhome before the end of 2018.

I'm talking from a first hand experience, I own a duplexes and townhomes on a slab.

Or is it just better to knock and face the disgruntled homeowner.5 - Does an investor just line up credit first and then go into the wild.6 - If the credit lined up via a bank/credit-union is for more than the price of the home, does it still require your own 20% down.7 - Duplexes/Triplexes/Quadplexes don't seem to be listed very often on many sites.

We are in a good place with our duplex in Southern California that we purchased February of this year.

Within the last two months I did what I thought was making my home “renter proof” got rid of carpet, added new appliances, repaired and painted walls, fixed up the landscaping for some visual appeal.

The ridge beam was bowed down and the front and rear walls bowed outward.

The handwriting is on the wall on this one. 

I think an FHA multifamily on a duplex to fourplex is the way to go

We had a GC on a duplex we were working on.
