A property in Haysville for example would be SW, but could also be filtered on "Haysville" specifically. 

Quote from @Gregory Chadwell: I wonder if having a lead filter installed on the property might help the situation too? 

Not much to add to the good advice already written, exceptYour mom could easily get a reverse mortgage to pay for her care, then you and your brothers could split the equity left upon sale.

If they are professional, they can explain this quickly and easily.

Can you travel there easily? 

But I would think they all can easily run the comps so you know the numbers you are aiming for in any given neighborhood/block/property. 

You can EASILY pass several million to your heirs tax free and avoid at least a $1M in taxes if you spend anywhere near 20 years investing in real estate. 

Here’s MY general feeling; if a MHP isn’t TOH, or I can’t easily switch from POH to TOH, then I might as well purchase an apartment complex and have less problems.

We work with a lot of OOS investors and showings, inspections, and lending can all be done remote very easily. 

But a bedroom or a bathroom can be easily qualified in terms of dollars (I usually see $4,000-$5,000 allotted for differences in bed/bath count).Truthfully, if I can't find easy comps and if I can't make it easy for the appraiser to agree with the value I'm looking for, I just don't buy it.
