Did they grill you extensively on experience (i.e. would a couple of successful projects be adequate).....or are they more asset/repayment based on the qualifying as long as deal is 80/20? 

I don't think that having one per 4 units is adequate so I'm guessing after a few times of going to do laundry and they're full most people just go to the laundromat.  

If you buy one, though, make sure to take off the top and check it out before you take it home--being natural, the veining patterns vary considerably from box to box! 

Just natural appreciation/inflation are going to have a huge impact over 30 years, and could vary quite a bit between what we expect now, versus what we actually get in the future. 

There is no natural political advocacy group for middle and upper middle class people who would like to buy or rent new housing. 

@Joel S. your FIL can't get a loan without adequate income so I don't think the VA route would work.

Else they'd  be the natural lazy selves that most are and sell via an agent.Search here on how to talk to sellers.  

I have a sales background, so this came pretty naturally to me.

If you are currently designing or installing a new fence PLEASE, STOP what you are doing and read this post now.Fences by their very nature are designed to keep people out, bring comfort, and relieve stress.

I personally believe if you  pay off all debt that isn't making you money and you keep adequate reserves available.
