We came upon this unique opportunity that could be a primary residence with income potential and we are weighing out whether it makes sense, and would value the input of those more experienced/distanced from the situation.

The reality is that most traditional lenders (whether banks to credit unions) will cap the loan term/tenor at 5 years with some willing to stretch to 7 years (may require lower LTV) as the lender portfolios those loans vs. selling them off like the owner-occupied mortgages.  

This financing is stretched out over an extended period and is at a relatively low-interest rate backed by the fed.

Using your 20%-40% ballpark (even though 40% on an old SFH is a stretch, in my opinion), we get about $30k per house.

The downpayment of 30+k IS going to be a bit of a stretch for us.

An Ohio attorney would probably be better to address uniquely Ohio issues.In that regard, I've found Ohio to be a relatively friendly state to operate rentals for over 20 years.

After further analysis, we realized this was an undiscovered opportunity and we continued to dig in an create our business plan with this unique fix and flip component.With the 4-unit we saw an opportunity to remodel 2 of the units and bring the rents up to market value.

It's a bit confusing because Denver has a very unique approach to zoning and divided individual parcel ownership.

But there could always be unique reasons why a hold period of less than (or more than) a year would be appropriate.You just want to make sure your obvious intent isn't to acquire this property simply to fix up and sell.
