So, make sure you include all the essentials in the kitchen, laundry, bathroom, and of course amenities.

Repair in damage likely did not increase the value of the home, this generally only happens through upgrades like adding finished square footage or major remodels of kitchens/bathrooms etc.

Have not had a 'issue' selling in the past five years..I would say the additional development cost of an extra bedroom/bathroom are probably well worth it in the long run..Good luck. 

Single family home, 1250 sqft, 2 bedrooms, 1.5 bathrooms, plus a 2 car garage.

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).

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.
