I'm a fan of the model you're using and is something I'd love to replicate.

Personally, I'm not a fan of Zillow at all and I'm an agent myself.I would find an agent that understands these types of deals and have them submit an offer that protects you as a buyer.

I am actually a fan of smaller annual increases versus larger increases less often.

I am also a huge fan of Zapier as it allows me to automate certain portions of my workflow/ systems.

I'm NOT an attorney but I understand Ohio Land Installment Contracts pretty well and I have over 30 years of experience with them as both a buyer and seller.There is a gray area that you'll need an attorney to sort out because if it "hits the fan", the following may matter. 

I'm always a big fan of small multi-family as a first-time investment.

I would paint the unit w/ white semi-gloss, paint the cabinets, and add a ceiling fan to the bedroom that doesn't have one then rent it for market rent...let's say it's $1,150.

It's been hard being a fan for the last few years.

I live in Salt Lake City and homes out here (while not as pricey as Seattle) are out of my league for investing.

I have a lot of friends and family out there as I grew up there, so I have an advantage but I'm a huge fan of the Phoenix metropolitan area and see a lot of opportunity.
