I’ll give you clean next steps and the trade-offs.I’m here to answer financing questions, share checklists, and post quick case studies that actually show the math.

This deal, on the surface, is not something that I would buy unless you think that you can outperform that Rabbu estimate or if there is a secondary reason (ie high appreciation, waterfront property for personal use, etc.).

I did some math and I found and area I can buy 3 brand new single family homes for around 200 each and rents are 1650 and they pay all utilities. 

We do the math 2 ways...what if they pay us and what if they don't and typically go with the lower number.

Indy is still a good market for rentals, but it takes a sharper pencil and sometimes a different approach to make the math work now.

soils matter and can make or break a deal but you can always pivot to a secondary exit strategy Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

With that being said, yes you can find 1% deals, but that's just back of the envelope math that says this property is worth looking into.

Happy to share what that math looks like if you want an example. 

Can someone help me to figure out the math behind it?

Aside from traditional duplex, tri-plex, four-plex:- secondary house - above garage apartment - walk out basement apartment I would give strong consideration to starting with the househack.
