What a room does need is 90+ square feet, ventilation and egress in order to be considered a bedroom.  

Recommend you go back to square one, and really think this through from an owner's perspective.

Or step outside to the lobby and network - you never know when an opportunity will present itself.As for most of the other REIA groups around the country, I cannot attest to how they operate (except for Dayton OH, Seattle WA, and Columbus OH).

the WA DC ones ?  

Hello everyone , can someone share what I could use as the square footage multiplier for a medium and heavy rehab in Fairfield county, CT ? 

It also has a 1700 square foot finished basement, and a brand new 3 car garage, with 1100 square foot luxury apartment above.  

Dig and remove around 200 square feet of an old concrete driveway, frame and lay down the concrete (concrete will be ordered from concrete supply business) and complete a brick ribbon around the driveway.

But it also had a small 200 square foot guest house in the back which we rented out for $1500.

I would split the utilities based on square footage of each unit, then add it to the tenant's bill.

I have considered adding an ADU in the back, but since I am limited to 75% of the main house square footage, this is also probably not worth it.
