@Kathy Henley yeah unfortunately I had to fold .

The factors here are several layers deep...1- The threshold decision is rooted in local ordinance and zoning...if you're in an area with tight local ordinances you're fighting with the people that live in the neighborhood before you ever reach the city zoning folks...this can go one of many ways2- ROI on the conversion...you're first stop should be with a local architect...they are worth their weight in gold when navigating a project like this and will wade through the regulatory waters much better than you...and a simple phone call may be telling to whether the conversion would be permissible.The extension of this is the cost of the renovation in relationship to the rents received...the stars would really have to align to say you should spend a significant amount of cash to convert a performing building with 4 revenue streams to serve another function (but there is more to this)...and the cost of construction (and lumber in particular) is 5 fold what it was 1.5 years ago...3- As you indicated...exit...I think the only rational reason to convert a 4-unit would be to get condo status or single family/ shared wall and sell one or both of the units to an end buyer (you are basically paying the role of a speculative developer here)...this is happening frequently in locations like Olde Towne East and Merion Village...hard to demonstrate how successful this has been, but it seems far fetched reasonable consumers would pay the same for a  free-standing SFR they would for half of a "duplex" or condo, but who knows for sure.Either way you look at it you're in a residential appraisal situation on the comparable sales approach....4 unit buildings are still "single family" homes. 

But after that you just really do not want to crawl into a bed, literally crawl because there is no head space, or fold a table into a lumpy bed. 

The problem you are facing is what I will call the "crash paradox", which is three fold:1.

The reason I ask is two-fold.

I agree with Alex, if you can be it increases your pool of guests ten fold.

The difficulty with the BRRRR method is two-fold.

Like fold towels for storage a certain way.

If their mess is trash, consider more dumpster space.If their mess is junk mail put two covered commercial trash bins near the mail pickup station.Post a red paper folded in half on their door with tan masking tape at eye level.In it say you will stop by in a day or two to introduce yourself, include a baked cookie recipe, and a silly joke.The next day start door knocking (Saturday might be best).Spend 10 mins with each one just at the doorway, talking about the problems and ask for their help solving them.Ask them if they have any problems too, ie. maintenance way behind schedule, spooky characters in the lot at night, etc..You could also tell them if the problem is fixed in 90 days or so, you will hold a drawing for a $25 gift card to the closest grocery store--but they have to be current on their rent.If it's fixed--pay for the gift card, and do the drawing and let everyone know who the winner is.If it's not fixed, red letter tan tape at eye level, saying its not fixed, so no drawing, but ask the to please keep working on it.You might want to clear the $25 gift card with the owner though, some are pennywise, pound you know what.Note: If you are in a general area with Red/Blue gang territory don't use red paper, just use white printer paper.

Maybe leave it as is and use front loader machines - then you could put a folding table thing above the machines for more counter space.
