Or there is a version for 2 to 4 unit small buildings as well but then down payment grows to 25%.Or if you agree to live in it for 12 months you can do it as an FHA 203k rehab loan with as little as 3.50% down on 1 to 4 unit properties and use future rents to qualify for the loan size needed.

The area is 15+ acres up to 100 acres, my choice on the size.

What is an ideal amount I should have in my savings before I buy my first property?

My first rental It took me a long time to get it filled because I was learning all the landlord tenant laws and the screening process was new to me.

Does anyone have any reputable recs that can take on a job this size?

I get a rough overview of what people are asking for rents for rooms in my neighborhood and then I adjust my rent for the room I'm offering based on the size of the room, number of people sharing the bathroom that room uses, time of year I am trying to rent the room (I dropped the price a little bit in the winter months to keep vacancy at almost zero.), etc.  

In some cases the percentage of ownership can be higher if a unit has a better view even if the size and layout is the same.

Your best bet is probably to raise it to market rent on a month to month lease. if for some reason you do not agree with month to month leases, then give them the opportunity to apply and be screened before their lease ends (I would pay for the background check in this situation.)

But it is a good size room and there is still plenty of space to spare.I wouldn't use it as a bedroom or sleep in there if I lived there, but wondering what is the best use for this room?

I have 12+ windows that are standard sizes and need to be replaced.
