Hi Joseph, You would need a 2 year seasoning period to qualify for a government loan (FHA) and a longer period for conventional unless you had a documented hardship situation, such as medical illness, etc where the loan can underwritten manually. 

Not going to be a huge cash cow per bed, but with the amount of people moving here (looking for a quick cheap sublease till they find a place they really like), students, and temporary IT and medical workers I don't see myself having any problems filling the other two beds for at least $400/month.

Another thing to think about, Columbia has two major hospitals and some smaller medical facilities.

The plan is to maximize the space we have and rent as midterm rentals to medical and business professionals.

Think isolated towns that are still a hub for rural communities, have a decent medical base, a college or two or three or military nearby. 

For example, if the property is currently vacant and you intend to lease to a medical practice, you should make sure the zoning regulations permit the use of the property as a medical practice.

When we do Joint Ventures with medical professionals, we explain the process in detail.

Quote from @Jacky Johnson: Set up some anti-barking devices: https://www.amazon.com/coprisin-Control-Devices-Deterrent-Ef...I bought these for my dogs.

It makes sense as a local because of the density of medical centers.

If one of your tenants gets bit by a dog, falls off a ladder, etc. and they have a bunch of medical bills they can't afford, they almost have no choice but to sue whoever they can to get the money.
