@Joshua Penners  If the tenants have signed previous leases and had uninterrupted occupancy of the property and continue to pay rent per the terms of the previous lease and their actions are consistent with the previous lease terms (for instance you have a $50 late fee in a previous  ease and they pay that now even though technically there is no new signed lease) then just about any court will deem them to still be subject to the terms of the lease signed or not .

If not (most people would find it very hard to have this conversation with their loved ones), then she can look towards paying a portion of their living expenses to ease the burden.

Thinking of it, even that small of a opening can have huge impacts of ease of going into the house from the right. 

That's not simple, because there is no basement or crawl space; the tub is installed over a cable-tension slab.One possible solution I thought of would be to take out the tub, reverse it and install it a little higher, with a slightly sloped, essentially horizontal pipe running under the tub from the drain to the existing trap, a distance of maybe 45 to 48 inches.

Maybe you find an area like that, one that you could technically drive to, but it have it managed just to put your mind at ease on this first deal. 

I'll research it further to put myself more at ease with it but either way I appreciate that information.

Its payed for (with our savings) and we are still waiting to have the remodel completed and to get lit eased, the estimate for the lease given to us was $700 to $850.

And my units have a lot of deferred maintenanceAt the end of next year the seller financing will be done, and an extra $4000/month will ease the pain.I think I will survive it, but in hindsight, life was great without them, ok with them but make sure you can let someone else manage them.

Marketing online can help you to find tenants quickly and with ease. 

One thing I haven't seen mentioned is the ease of property management when you live on site vs being somewhere else.
