Even cash-flowing properties could be undesirable for a bank’s risk appetite for refinancing.

It is very rare for a mortgage company to miss out on protecting their first lien position by redeeming the unpaid taxes.That's why the tax deed sales are usually a waste of everyone's time - the good stuff is almost always redeemed and by the end of the auction, only the tax deeds secured by undesirable properties are left standing.

There could be very undesirable people such as child molesters or convicted felons staying on your property so I would at least want them to not have access to the part of the house my family stayed in. 

Slightly concerned that I might catch a bunch of undesired feedback.

Quote from @Eliott Elias: One bathrooms are undesirable for tenants and buyers.

And I strongly suspect that Tenant Alpha ALREADY let his brothers move in a few months ago, without first getting our permission and approval of the new occupants, which may be why they stopped paying rent at the other place.CURRENT QUESTIONS AND CONSIDERATIONS: This house will remain a long-term rental buy-and-hold, and since there are a lot of things that make these tenants undesirable to most landlords and lenders, I believe they likely won’t be able to find anyone else willing to sell or rent them a place … which means they’ll likely stick around long-term and pay timely.
