Reason why is if you go to sell it, people are not going to comp it based on 40 year loan.

Quote from @Samuel Hudson: Hello friends I am new the market and recently bought a home in Weehawken 6 months backs .Its a three family home and we are currently doing renovations Right now.The rent leveling board told me that two units would have to follow a rent of 1650 for unit 1 which has three bedrooms and another unknown amount for unit 2 which they don’t have the information for .The previous seller I purchased the property from bought it as a tax lien .He has kept the property vacant for two years with no tenants before selling it to me .However ,the previous Owner he bought it from must have had tenants .I am putting in a lot of money into renovations and want some clarity on the situation I am in .The property has been vacant for the two years and currently still is as we are doing renovation .It would be really appreciated if anyone can assist me on what information needs to be provided by from the previous seller for me to be able to set the rent based on the market value .Thank you .

I joke that he's the unofficial Mayor of Springfield based on all of the social and charitable activities that he does there.

I was asking with the assumption that I can at least manage the property myself, but based on the documentation they provided it seems like not if I don't have a broker license myself...

Anyone have a cheat sheet or checklist for covering your ADU bases?

Tiertiary markets can get you to 1% rules on paper but then it'll all be based on demand and tenant class.

It would still be based on the revenue it produces.

From there, you can research through zillow/redfin whatever but your best bet would be to find an investor/agent (I a one but based in Fort Lauderdale) who can guide you through the process.
