Given the likelihood of small portfolios, your debt maturities will be heavily concentrated, even in a fund.  

But on the flip side, it must be exciting to own properties scattered across the United States instead of them all being concentrated in 1 or 2 spots.Which would you prefer?

If you have a high concentration of single family homes and no multis, chances are it's not going to be on the radar of those looking for a rental, unless that town has some endearing qualities that people really want and are willing to pay for rental wise. 

I used a ozone machine in a cat pee house we flipped, it helped but  also got super results from product odor medic I had tried many others and this finally did the trick.. it's a concentrate you mix and do light spray.

Customer concentration, lack of systems, etc.  

There are couple of lenders that concentrate in non-recourse lending and usually the terms and condition are very similar across all lenders.

If you scale the business you need to be in a more concentrated location and you are in trouble.

From my experience BP does not concentrate on any one specific region.

The returns are worse than in crowdfunding and you have concentration of local economy risk, however I like the risk reward there better than crowdfunding.  

I am concentrating in San Juan: I own multifamily and currently looking for vacation rentals or buildings with 20+ apartments in it.
