It was a great first project, I had some old friends reach out that were losing their house and I helped them get out from under the PML, bought the house and helped them repair their credit, got a contractor I knew that lived around the corner help me do a full gut rehab and put in about 1,500 hrs of my own labor into it.

When I say large I mean $250mill projects +.

I agree with @Don Konipol, if the overall cash on cash return for this project is only 10%, it's not a viable deal.

Should I open a separate HYSA or similar vehicle to park additional cash reserves and or taxes set aside from prior projects?

Some land flippers will buy unwanted and neglected parcels of raw land for a bargain and then improve them by clearing the land or even leveling it before selling it on.Most land flippers are making money by actively seeking and marketing their land flip projects.

Naturally my biggest hurdle is the capital to fund the projects.

Every project is way different, too many moving parts in this business....

I use term policy and invest the difference to fund a whole bunch of projects, too.

Projects can also take a lot longer, and cost a lot more money, which can have a significant impact on your bottom line.

Based on those numbers for a small project, I would say that's not too far off.
