I'd recommend looking at costs. your build cost is going to be well over other homes because of the fixed costs like slab, Hvac, roof, etc. check the market drivers and weight the benefits of short term versus long term. long term is no furniture and help pays mortgage but at this size it doesn't really cover everything. we didn't find a lot of economies of scale in single family detached. can you build more than one unit?

I use the individual stackable units when I have space restrictions.

Final bit of advice: if you can, steer clear of house hacking and multi-unit. 

So this reason I rented the unit.

Duplexes are a little easier than 3-4 units with FHA since they don't have to meet self-sufficiency requirements.

Since your an estimator are the materials and labor based on facts (i.e. hard costs a labor units) or a guess.Nothing personal but I wouldn't consider anything you wrote there, if I was buying I'd do my own estimate/SOW. 

I just invested in batch leads (wasn't happy with prop stream) and am using a virtual assistant to help cold call some absentee leads from there.  

This works best when the seller is motivated and open to flexible terms.4.BRRRR Strategy (Buy, Rehab, Rent, Refinance, Repeat)– If you find the right undervalued property, you can finance the rehab with short-term funding and then refinance into a long-term loan, pulling most or all of your money back out.5.House Hacking– If you’re open to living in your investment, you can use an FHA loan (as low as 3.5% down)to buy a multi-unit, live in one unit, and rent out the others.
