Sit down with them and lay out your thought process. 

I'll sketch out the (current) terms first and then lay out my concerns/questions:Proposed Terms/Assumptions:- I contribute my land to the project receiving accrued interest at end of project (at rate similar to hard money rate).

I use Chief Architect to do layouts/constructions drawings and can handle any permits needing pulled.I have capital that I’m willing to invest.

I am really wondering if someone can layout how to jump into it and go about completing the BRRRR method.

Our portfolio in Illinois (close to Chicago):All properties in this portfolio are the exact same layout in terms of sq ft and having 2 bedroom and 1 bathroom and are Condos in a 4 unit building Only difference is when each unit was renovated or not.

That is a better way to start than pumping numbers from Zillow into a spreadsheet before you know what to look for in a basement or layout.

If you would like real numbers  on what you can potentially borrow lay out what you currently owe and what you think the duplex is worth?

You have your standard two-family layout.

The type of tenant you get in commercial heavily varies on the economic status of the local economy, as well as the layout/who you're catering too.

Don't settle for shallow observations; instead, delve further, ask meaningful questions, and follow your intuition.
