I had to present my documents for setting up the LLC and also my EIN number.

I found this fact sheet which seems to indicate it would be possible to evict the rent stabilised tenants so long as they haven't been living there for more than 15 years or are older than 62 or disabled: https://hcr.ny.gov/system/files/documents/2020/10/fact-sheet... 

Verifying last 2 years of rental history very important!

If you have a stable asset, predictable returns, and a lease structure that’s well-known and well-documented, a regular market valuation might make sense.

Do you have anything to justify or document the "below market price" like an appraisal or even BPO? 

Re-read your contracts, document your correspondence (and attempts) with your builder and demand documentation to match up any payments/draws with what's actually been competed on your build.

If you do not want your name to show up anywhere on the closing documents, you would need to get a power of attorney to allow someone else to sign on your behalf. 

Unfortunately screening is getting more and more difficult with workforce, big name companies changing their policies to not sharing rental history.

Even if they stopped reporting your payments the history would be there. 

Since your metric is modest cash flow with long-term appreciation, focus on neighborhoods with a history of steady growth and tenant stability.As a realtor, you already have the skills to analyze deals—so trust your instincts and take action!
