They just want to get in, get out, and move onto the next.To be fair, I had an "aesthetics only" rehab (20k give or take?).

Aesthetics are important.

I would remove it for both aesthetic reasons as well as possible foundation issues.

Then design it aesthetically in a way that would be attractive or inoffensive to 8/10 of them.

Do I go with aesthetics or the somewhat higher durability?    

If it were my rental, I would never install a black fridge or something not aesthetically pleasing.

Insanely good looking flip from the aesthetics/pics!

I improved the aesthetic and energy efficiency of both cottages.

I don’t want to set the tenants up for failure with a bunch of differed maintenance and I also want an aesthetically pleasing park, so I’m in the process of a rehab.I’m willing to finance all of the trailers to the tenants on terms that would make the monthly payment + their lot rent the same as, or less than market rent.

A few other reasons I like build to rents vs. typical rentals: they attract great, well qualified applicants, they usually bring 2 year leases, we're able to incorporate the details important to us into the home for aesthetics and durability, everything of of course is new, so a lot less maintenance calls, last - they require a lot less effort to manage relative to more common rentals.
