So we chose that route and repainted, added baseboards, refinished the bathroom cabinets, added granite to the kitchen and bathrooms, added used stainless appliances, and cleaned up the yard and house.

It's a 4 bedroom, 2 bathroom house, both bathrooms are fully renovated and the kitchen is 95% renovated, just needs that wood paneling removed.

There was an unknown water leak in a pipe between walls at my primary residence ( betw master bathroom and a bedroom.

Anything that turns into a bathroom visit later is 'dropping' in value fast:)  Drive a functional beater that needs a name.  

Then I check the other bathrooms and HVAC and notice no leak as well.What might this be?

I don't find airbnbs auto-pricing to be accurate at all and it frequently quotes rates for me more than half of what I know I'm able to fetch for my place.I would say this is probably because I would imagine it would be hard to code a system that takes into account quality of amenities, true location, size, and unique features.What both systems likely do is just dig through all the listings of homes that are around the same bedroom and bathroom size and then give you a price based on the average of those homes, but that leaves so many important factors out of the equation such as the quality of the house, the true location of the house to tourist attractions in the area, quality of amenities, unique amenities and the houses reputation through reviews.I think the tried and true way to accurately price your home is to simply dig through the listings and find houses that truly reflect and in accuray to your own house, see how much they're booking for through the listings calendar and then price your home similarly to theirs.

A standard tile ceiling typically wont hold up in a bathroom due to moisturize / humidity.  

Additionally, older properties may have used poor or unsafe construction materials (like asbestos), which you may have to replace.Beds/Baths: Different areas will have different prevailing bedroom and bathroom configurations.

It consists of 2 separate office spaces each having 2 offices a nice big entry and a bathroom.

--I've budgeted no more than $140,000 for a near total renovation (roof, siding, re-wire, re-configure, addition of master bathroom and relocation of first floor powder room, etc, etc)--Comps justify an ARV of +-/ $750,000.
