I would make sure all of the utilities are in one corner of the basement so you can easily hide them or include them in a storage room.

Hi Everyone, I'm looking to convert a 425sq.ft storage area into a 4th unit in a small multi-family property. 

Keep in mind all measurements for storage are relative.

You could also generate some income that can make buying look better (house hacking, renting storage space). 

Full basement with tons of storage space, washer/dryer and fenced backyard.

Storage is always good in a bathroom. 

Anyone here done analysis on Post Modern Portfolio theory and have any data on things like Sortino ratio's for the different asset classes like multifamily vs development or self storage?

Someone completely gutted the inside down to the studs and reframed almost all the interior walls..Floor plan was changed started by relocating a new set of U-shaped/ half landing stairs possibly 45-48 inches in width from the basement up to the main floor and beyond into what looks like to be an attic for storage on the front of the house and may be large enough for another bedroom on the rear but if not just more storage..new furnace/AC also ductwork to half the house and new electrical was run in some rooms but still may need to be finished in interior walls .

I haven't had much experience with any BRRRR types of projects, which I'm definitely interested in, but I guess I'm just curious what some of your guys' next move would be if you were in my shoes. 

From a commercial RE perspective, I would suggest looking for opportunities that are less risky in today's environment: industrial, mobile home parks, self storage.
