Hey @Steven Graber, I haven't heard of the guy or company you mentioned. I'm local here in the Detroit area. I purchased my first 4 properties in the last three months. I'm self-managing, and I'll be buying at least four more by the end of the year.
My first bit of advice is to be cautious. I have zero knowledge of any "turnkey" operators in the Detroit market, and I'm quite active with local meetups, private Facebook groups for Detroit investors, etc. IMO the margins just aren't there for turnkey folks. I've met people that have purchased what they were told are turnkey properties only to have to put tens of thousands of dollars into them in an effort to get them rent ready.
Search the forums, Detroit is an extremely unique market. You need someone on the ground you can build a long-term relationship with if you're planning to take investing here seriously. PMs here are also notoriously terrible.
Feel free to reach out if you have specific questions. Happy to give you my quick two-cents on any properties you're considering. But again, I'd warn you on dipping your toe in without a bulletproof plan to acquire and manage the homes.
