Of course after a few deals, he/you will gt better at putting a number on the project, but you may have slim or no profit on at least a couple of jobs.I had decades of experience and a partner with unlimited deep pockets, and still lost money on a flip!

I would like if you ever need a licensed GC to do renovations/Tenant Improvement projects I have a group for that.  

You're analyzing every possible scenario, every potential risk, and every projected return.

I have a template that I use that includes projected income and projected expenses and I run the calculation myself, but if you like ones that do it all for you in addition to what has been mentioned above AirDNA has one as well.

Getting a construction loan without formal building experience is possible, but lenders often require a licensed builder or contractor to oversee the project.

We can usually use projections from air dna.

I do need some cash flow from the investments for other unrelated projects.

Part of the funds is held back for a cushion or if something unexpectedly happens but can eventually be used as the project is closer to finishing up.

Thanks for that Lets just say the seller makes the upgrades that's needed and rents for close to my projection's rents or lets just say as it stands how would you make this deal work.Thanks

As @Ke Nan Wang said you have to hire an architect to make these decisions for you.On my projects I will compile like 5-10 inspiration photos based on projects I've done in the past, comps, and photos I find online, then I'll present those to the draftsman/architect.
