Then get it ready to rent.

Is not a new construction, rather making it a liveable place, so I could rent it later on to at least cut my mortgage payment in half and be able to focus on other investments. 

We’re long-term rental property owners, with a condo we’ve owned since 2009 and rented out since 2013.

Say that you need to move in to one unit and raise the rent on the other.

Usually, I rent my rooms for long-term rentals with a minimum 6-month lease.

Fairfax, VA is a strong area for renting out properties.

I'm hoping to purchase something that is move in ready with little work required to make it more appealing to renters while charging max rent.

Rented with two different tenants getting $1700 month.

We aren't using the garage at all and aren't planning on doing so, so we thought on making it a living space separated from the house for rent, which we'll sacrifice 1 of the bathrooms to add it to it, and later on do the same with 1 of the rooms as well, though I would have to make an extension to add the rest (kitchen, bathroom, etc.) so that way we could take advantage of the space we aren't using. 

Thank you for your advice.Depending on where the property is in Columbus, you may not need central AC to get it rented.
