Tenant had bf living with them I made bf sign lease amendment to be on lease. 

Is there legal recourse for me to now collect the required security deposit from the tenant even though he is in place (his lease does not expire until 7/2025), can i do a lease amendment requiring payment?

You can try to make it part of the inspection amendment, that's the last time you have some negotiation power.

After the lease is signed, you can open the security deposit account and then provide the tenant with a formal notice that includes the account number, bank details, and interest rate.This notice can be a simple letter or email, which should meet NJ’s requirements without needing to amend the lease or have the tenant sign it again.

“Our manager will reserve the right to reject any share repurchase request for any reason or no reason or to amend or terminate the share redemption program,” the company said.

Along the way, we see so many folks make mistakes that they need to get amended and that can take years to finally recoup all of the money lost from paying to much. 

You can do this with a simple, one-page addendum, or even a written statement added to the existing lease and signed by you and the tenant.Example:This lease agreement is hereby amended to reflect the change in ownership of the rental property located at 123 Straight Street, Cody, WY 82414.

Lots of houses have flood designation amendments if they are up against little creeks, so they wouldn't disclose any issues because they had their boundary inspected and ruled OK.

For anyone following: It cost me $5 to file the updated statement of info and I simply drafted an amendment to the existing internal operating agreement to clarify our intent to operate as a married SMLLC. 

@Jon Fletcher There are basically two potential options. 1) Amend the tax return in the year of purchase and prove you used capital gains to purchase the property and 2) Sell the property to an OZF, follow the 20% related party rule and then the structure of the sale of the property to be able to reinvest the gains.
