I just mean to say that I don't think there is anything wrong with their business plan, their operational expertise, and so on, so unless something melts the economy down, it seems as though Brian integrity of the operators is the only remaining variable. 

Land leases often complicate financing, limiting your buyer pool, especially if lease terms are unfavorable or the remaining lease duration is short.

Would recommend you read a couple books about BRRRR, that will give you the basics and then feel free to reach out.It remains a great strategy, but you have to manage your expectaions.

Get knowledge, follow experienced people, and leverage wisely.My Take:If you have two houses, excellent credit, and motivation to build wealth, you can learn to manage your money responsibly.Use HELOC, credit cards, and business credit funding to leverage your cash and buy properties faster.

I was considering reading J Scott’s “The Book On Estimating Rehab Costs” but wasn’t sure if the information remains relevant 6 years later given how pricing has changed since then. 

The remaining “residual” cost is then assigned to the building itself.

@Arianne L. 100% agree the "why" is what keeps you focused and motivated.  

FHA allows the construction or renovation of an ADU on the property by refinancing into a 203k loan, but the property must remain your primary residence.This stuff is subject to change, lender specific, and subject to other factors.

And it wouldn’t even be ONLY profit motivated.

Pretty much everything I have seen and read is:Find out the sellers motivation/problem and speak to solving that issue.Give an offer but explain how you got your numbers.Other than that, it seems pretty limited for negotiating information.
