As a side note regarding craigslist: I once purchased a washer, dryer, and refrigerator all for $125, put the washer and dryer in a rehab and sold the refrigerator by itself for $175.

When I saw her in person, all she was selling was her 2 books.

It needs washer and dryer hookup installed and washer and dryers as well as carpet..

Do you or anyone else recommend utilizing this space for personal storage, or leaving the building only for tenant use and perhaps closing off the attic and providing coin-operated washer/dryer in basement?

Things like updated kitchen and bathrooms, in-unit washer and dryer, dishwasher, covered parking, fenced back yard, community pool, rec room, etc. may all help increase your rents, but you have to know your market and your target tenants.

It was her fault she didn't even look at the file when I sent it back.

I don't think it would be worth it unless you did it to scale.Buy a decent, used washer/dryer set that is just a few years old for under $500.

Washers/Dryers, Microwaves, Coffee Makers, etc. 1 button operation or super simple is best.

There was no kitchen so she took back all that was hers.

We did a remodel when we hit 10 people to change the laundry room into a 3rd full bath with shower and make the 1/2 bath a full mud room so we could have two full size washer/dryers.
