The first thing you want to do is have a proper chart of accounts.

You are probably looking at possibly subdividing the lot into another single family lot (if you have enough frontage and lot size per code).

The amount depends on the size of the storage unit but mine range from $15-25/month.

Make sure you are asking for a good sized deposit, and when renovating, use materials that are hard to damage (LVP on the floors, higher sheen with the paint, higher quality faucets, maybe solid doors).

The larger size and lower monthly fee of the space lends itself to being a better option than local hotels.

Each has its own unique "issues", and require different skill sets.Class C - "Mom and Pop" rurual facilities non climate controlled, smaller in size.  50 to 200 unitsClass B - Second generation, suburban, may be climate controlled, mid sized.  200 to 400 units.Class A - Urban, fully climate controlled, larger facilities.  400 - 1,000 units.

@Sarah Davis 60% vs 55% of a typical lot is about the size of an efficiency or an adu.

Mini Splits are a great way to heat and cool units that size, however maintenance can be costly with tenants. 

Typically you can get a LOC of 40-50% of your portfolio's size depending on the investments you hold and brokerage.
