It can be a simple one page contract b/w you too at an agreed upon rate.

I'm under contract on grand fathered 3 family that is currently being used as a 2 family.

Its generally retail medical operators, so we include things like the market dynamics for our use and why statistically the market and location of the site will be viable form a business case standpoint, and speak to how the startup has enlisted the help of an EMR or other such consultant to help in their general rampup and ability to bill/get insurance contracts.  

Please be aware that all national homebuilders, and I would assume solar developers as well, will want enough time in the contract to conduct substantial due diligence, rezone (if needed), and get all required land development permits in place before closing on the land. 

Both tenants moved out while I was under contract to purchase.

As long as you specify the bank name, address, and interest rate in the lease, you're meeting the legal requirements.To avoid the hassle of having to have the tenant sign the lease twice, you can simply leave the account number blank in the lease and note that the deposit will be held in a specific account at a designated bank.

I was told I need to get a good understanding of these subjects:  1) Taxes, 2) Legal issues in ABNB, 3) Negotiations, 4) Short Term Rentals & 5) Tenant/Rental Agreements.

U know when the settlement statement comes in there maybe 1 point but 5k in junk fee's that are disclosed until basically the day of signing as they are not legally bound to disclose all their fee's up front like a NMLS state licensed owner occ loan.
