If you are thinking it's just for a few days, consider renting a U-Haul truck and parking it in your driveway. 

@John Chapman  I know I paint a broad brush.. but if your unlucky enough to get a house that settles 6 inchs because of soil shrinking.. then you have to deal with it.I have one left and god I hope I can get it off the books in the next 60 days.last one I sold while in escrow monster hail storm had to replace roof had to postpone sale had to pay deductible   all in all cost us about 4 to 5k ... and owner got a brand new stinkin roof. 

I don't really think there are any cons--you're going to vet people just like you would anyone from Monster or Indeed.

Recently I read an article on bigger pockets, about a truck driver using a hard money lender to buy multi family units eventually quitting his job etc etc, how does this process work?

You could tow a small RV with your work truck to have a place to stay before you find a property, and then park it on the property you find to avoid living inside a construction zone.Another more realistic way would be just work as a travelling contractor or other professional (eg: insurance adjuster).

If you buy something that yields good cash flow and your investment trucks along as planned, you can deal with selling later.

Due to a big steep hill, we couldn't get a bucket truck or machine around the back of the property.

Kyle Kufeldt yea man I feel if I can get it going it can be a monster.

I've gotten 3 quality tenants this way: a bakery, a wood fire pizza food truck company, and a Mexican food truck company.
