I'm in Maine if it helps, and not Portland/Lewiston but a rapidly growing city no less.

Specifically, there's job growth (Intel, Honda, Amazon, Nationwide, etc) and the population is growing (unlike Cleveland or Cincy).

With how much the Raleigh area is growing it seems like there is endless opportunity down there but I have struggled to get traction due to my lack of industry experience and local network.I would love to talk with anyone who would be willing to offer advice or lend a hand in any way. 

If the SDIRA owns the home can I ever use it as a primary residence in the future?

I agree with Glen, you are unlikely to ever see the unpaid rent.

If you look at cities that are growing, such as Jacksonville, Nashville, Tampa, Dallas, and our favourite - Phoenix you will find great deals in C/B areas that have great cashflow and will also appreciate.Expect to pay more than 39k (also remember to include the exchange of 30%) but a lot less than $300k like that property in Peterborough you mentioned.

That city is growing, wonder what kind of tenants MTR would bring.

I am going on year 2 and I absolutely love what I do, but I don't think I will ever be someone who enjoys a structured 9-5 office job.

If you're growing and taking OPM, please use an attorney.

I'm really interested in just having properties that break even and grow in value until I retire in 20 years.
