These examples were both smart people mind you (one an engineer, the other a doctor).

I work as a marine engineer but looking to dive into the world of real estate investing.

In 2023, I had a partial property line survey performed by a local engineering firm.

Thank you. you can reverse engineering the process , most of these note company are regional or even city wide only, so someone that's offering loan in Alaska would not been able to provide the same in state of Florida for example, so there should be a license that's allowing those company. 

Working in their favor has also been massive appreciation in many markets and robust rent growth.

A lack o robust team and systems that you can see and meet. 

He has a very robust team that I also do a lot of business with.

I can recommend a local architectural/engineering firm (previous office was on 36st in Astoria) that is very experienced, knowledgeable and professional.All the best to you & your dad on this next chapter!

The wall out of level could be some settlement , get an engineer to look at it .
