Any concerns w/ Class A multi-families now including self-storage options for their residents?

We bought that house in 2006, so as you can imagine, we are still underwater where LTV is concerned and our monthly NET is at a break even point.  

Hence, no need for a private lender (unless they need to use one to finance the home before the option expires, and they've exhausted all other possible permanent financing solutions in the meantime).

They risk becoming a permanent blight in the neighborhood.  

@Karl Johnsonyou can set a fee to set up the deal and marketing for the buyer.Paid by seller, buyer, or both.Land contracts, wraps, and free and clear installment sales also can be contracted for.You can not guarantee the performance of buyer to receive permanent financing in the future.You must use a RMLO - registered mortgage loan originator -  to protect the seller from buyer creating a lawsuit over Dodd Frank's Ability to repay rules.You must use a payment serving company to protect the buyer from seller not paying the PITI.Once you learn these strategies, you can assist pretty house sellers sell on terms and challenged home credit buyers buy on terms.Caution: Make sure buyers go through the RMLO.

As far as the loan will be concerned they will be "single family." 

@Zana Blue How gracious and humane of you to even be concerned.

Owning guns is a pain in the butt in CA, so I'm relatively light on the guns but have various bladed instruments staged about our home (that I own, obviously).The hoarding is the only thing you described that strikes me as unusual.This dude probably wants to do what is expected of him, which is not causing permanent damage to the property and pay his rent on time, in exchange for basically being left alone to quiet enjoyment of the unit.

@Derick DavisThat upcoming correction does concern me.  

Be concerned with how much money you can make off it.
