@Danielle B. when buying out of state you have to know the people you will be working with. You can build your own team i.e. title co, insurance, pm, contractors, handyman,process server, lender etc.... or you can find an operator who can get you going in that market while simultaneously building out your team.
Section 8 housing is a great way to ensure consistency with rent payments however not all tenant who have HCV pay 0%. Many times the tenants are income based and pay 20-40% wherein only 60-80% may be guaranteed.
Aside from the rent percentage issue is pride of ownership. Sometimes the tenants are coming from shelters or other communal type of housing where maintaining a space my not be solely there responsibility so maintaining the unit may not be to your liking. Not in all cases but more often then not.
Additionally you have to have solid management who is checking on the property at a minimum once per quarter as many times I find these tenant don't always report issues timely.
Is it a great way to ensure income consistency? Yes, but you should really be involved at the outset.
There are so many other nuanced things to discuss but I'll leave it right here for now.
Best of luck!
