You have to furnish so you will have increased cost (lots of consignment shops and habitat in the area)  At the prices in South County you have to rent summer and winter to make a profit. 

Volunteer at Habitat for Humanity. 

Rather than work on my own houses during rehab though, I volunteer on weekends when I can at the local chapter of Habitat for Humanity and have picked up quite a bit of construction knowledge there. 

There are lots of resources (sketchup and the like) you can use for space planningIt will make you a vastly better investor in the long haul.If you need experience to get started go work with habitat for humanity, and learn how to build a house, which will teach you how to rehab them.Obviously hire out electrical work or any plumbing that involves, major reworks, but otherwise you will benefit from knowing how to do all this stuff

It'll be nice to be able to take the next few months and look into what it takes to do a successful house hack and maybe even take time to hone your renovation skills by volunteering for a nonprofit like Habitat for Humanity or working on a friends' project.

@Sunny Pyun I actually found a Habitat Restore in Newburgh, by accident.

Here in NY if you're caught relocating wildlife it's a $500 fine because you could be spreading disease to new habitats.

I will also pick up a few cans of paint with out them being mixed with color, and if I'm out of a certain color I can go get a can color matched with extra stock I already have on hand and have paid  1/2 price on.Tiles: I will go to a "re-store" or habitat for humanity store at least once a month to see what they have in stock.

Volunteer for habitat?

Any materials: Lumber, plumbing, fixtures, cabinets, lights, tubs, etc.One source I have to share are Habitat For Humanity stores: https://www.habitat.org/restoresYou won't find inventory online so you have to stop in, but they have a very large stock of discounted donated materials.
