The property seems to cater to the lower end of the market but attracts some doctors, social workers, and related and unrelated types of businesses.   

I've heard of Realtors charging a minimum buyers fee on lower priced properties and it could be a policy by the broker and not the agent themselves.

The upper 2, or the lower 2, but not all 3.

These are definitely lower-income individuals, so I understand that the options are very limited. 

Yes it can be fixed and again the LOC would be re-evaluated for a lower rate each anniversary year.  

Unfortunately HUD's definition of a service animal is much lower than ADA's definition but I have threaten to fight this inconsistency on a couple of occasions and both times the tenant backed down (We never went to court).What sort of asset protection do you have in place?  

I have, on multiple occasions, asked my clients to lower their offer price, and they have gotten into contract on those homes! 

But in our case we just bought it last year for cash and the sale price was lower than the previous appraisal so no problem asking for it to be reconsidered.  

Lower cash flow rates are a common side affect of the BRRRR strategy.  

It would seem hard to negotiate a lower asking price if the seller needs to sell for what was owed on the house.
