If you property is functionally obsolete like only has 1 bathroom, adding a bathroom would likely pencil out.  

You'll get lots of bids from different cleaners once you post an offer with your house details (size, number of bedrooms, bathrooms, location, etc).

We have the grip strip type TrafficMaster Allure in a bathroom, holding up well for several years now.

I just completed a rehab that comps show a half bathroom is worth ~$50k.  

Should be way less than $40-50k, The Container Stop quotes around that for a 20 footer with a kitchen and bathroom 

I am looking at the following deal:Address: 4116 Jason Rd, Spring Hill, FL 34608Asking Price: $650,000Property Type: Multi-Family | QuadPlexBedrooms and Bathrooms: 8 Beds and 8 Baths | 4 UnitsSquare Footage: 4,644 Sqft | 4 UnitsCurrent Monthly Rent: $5,525"This property comprises two fantastic duplexes built in 2007, which share a lot and feature a private screened-in pool.

STR cleaners generally set rates that average out, meaning the big stays that mess up the whole house are offset by the one offs that use one room and the bathroom and never touch the stove or refrigerator.

The house is a 3-bedroom, 1-bathroom, 1,300 square foot home currently undergoing a full renovation (interior).

Another longer-term renter was shooting porn in our clubhouse bathrooms.

It is a four bedroom, two bathroom, split level house needing approximately $20-30k of repairs.The purchase price is $177,500.
