This is the one question I’d add to your otherwise strong list of interview questions.- Doubling the penny every year for 5 years is really tough and really risky if it’s not your full time job.

Ultimately, I'd like to have 3-5 paid for properties heading into retirement at 65.

If so I'd love to hear about your experience and what you like/dislike about the area.I'd also like to know if you have any agents you've worked with that I could reach out to.

I'd be happy to help you locate properties that fit your criteria!

For me, I'd probably ride this out.

I have a graded map of Ohio I'd be happy to share.

I’d make sure management got that in writing from the tenant as they must allow access with proper notice so they’re likely violating lease.

I'd go for a single family home. 

I didn't ask them about MLS deals, but I'd bet 95% or more of them get done.Ask your main title company how many of their MLS deals close vs how many of their wholesale/off market deals. 

In addition to checking out @Jim Pfeifer’s Left Field Investors, I’d recommend you go to Ian Ippolito’s Real Estate Crowdfunding Review and his Private Investor Club.
