Make it a master suite or something like that.It looks structurally safe, they intend that Attic to be storage so weight shouldn't be a problem. 

All he would have to do is rent a self storage locker and put the motorcycles in there as well as his endless collection of tools.When they moved in I was there and didnt see any of this hoard. 

RV parks, mobile home parks, and self storage all are great options.

I will spare you details like falling out of contract due to windows being inexplicably nailed shut, but for comedic relief I will highlight the pain culminating in complaints that there were random, free-roaming chickens pecking around our yard and putting off potential buyers due to a negligent neighbor.We ended up needing to take it up with the city to reign these fowls in, an action that caused the spiteful neighbor to tank a number of our other showings.The end result of all this was losing at least $30k (and probably more when it was all said and done), locking up the capital for ten months, and dealing with a two month long, stressful process of trying to sell and falling out of contract three times for various, silly reasons.

I've considered Airbnb-ing a room, petsitting people's dogs, using it as a storage space for people.

A standard refridgerator is wide enough to hold a 1/2 barrel and a pony keg and a 5 pound CO2 tank. 

Doing this will temporarily tank my score Im sure.

I'm assuming the $12,128 is not just points,  Hopefully what you have in there is:  your lawyer fee, title insurance, inspection fees, survey (if you want one), oil tank sweep if necessary, misc. costs. 

If the market tanks, you can hang on until recovery.

At the end of the season I will turn off the main water valve, drain the hot water tank, open all faucets and drain valves to drain pressure side.
