Depends on the area and how far out your core 4 will go. Lenders and agents may be more willing to handle different areas, but contractors may charge extra or just refuse to go outside of their area. I've stumbled upon a few service companies in my area that only service about a 15 mile radius. Also, it's probably going to be really difficult to find management companies in rural areas. I've heard that complaint from a lot of investors that I know.
Thanks Cassi, I suspect that will me my issue too, finding management companies.
