I would check the rent per month the new house would command again.

More often than within MLS data, it is property owners listing for as much as they can realistically command there. 

But in this market, the right portfolio can actually command a premium.  

I live on the prairie, where wood fireplaces are uncommon and having one commands no rent premium.

Those are out there, but would command 7-10 k.  

for single family rentals it doesn't command a price premium from the renter but does cost a significant price premium to install.

Our lake house is in north Idaho.I would not do a mobile home, you will not command a high nightly rate IMHO.This is a modular factory built home FYI.

Obviously any specific tenant might treat your property very well, but tenants in general could start to cause issues with your finishes and then you'll lose the premium you might command today.

Additionally, there is substantial supply constrained in such markets, so if you are planning on renovating units to a greater extent than the competition you may be able to command rents that you'd never be able to validate in existing comps.

Third, the risk is that we don't get our anticipated sales price and we keep more units in our own portfolio -- wouldn't be the end of the world given what STR's are commanding in Asheville right now.
