Purchase price: $419,000 Cash invested: $42,000 Sale price: $543,000 Fairly quick flip - flooring, interior & exterior paint, electrical recessed lights added, minor tile work, and new appliances.

Interiors typically have floor plans that layout core/shell and tenant spaces. 

A JADU is much simpler than an ADU; basically just a bedroom with an efficiency kitchen, bathroom access and access to the main interior.

Repaired, exterior brick, interior paint, exterior paint, new bathroom surround, fixed windows, replaced doors, added closets, and updated fixtures and appliances.

There are plenty on newer 3/2 in area just south of 610 that a builder is building to rent. 3/1 in this area will have higher days on market and lower rent even though this interior rehab was done well.  

I can not get a loan for 700k, conventional or FHA due to interior. 

The 2nd one was more complex and recent, much more paperwork, pulling comps, and showing interior pics.

I had a client that added a bedroom with no exterior walls, just 2 interior doors leading to other rooms or area of the house. they had to put a skylight in order for it to legally count as a bedroom.As to your sketch, the room with the fireplace appears to be a family/living room, not a bedroom, and the realtor is just calling it a bedroom, to make it more desirable.

I slowly changed the interior over time (paint, flooring, cabinets, baseboards, shower What was the outcome?

My properties have decreased significantly even though most have brand new roofs, siding, complete interior rehabs etc just within the past 5 years.
