Find a great real estate attorney to help you with:1) Putting a lien on the property, with your aunt's consent, to cover any work you do.- Ask the attorney if your aunt & dad need to authorize lien, or just aunt.2) Understanding your options to force payoff of the lien.- Ask attorney how you can enforce collecting on the lien when you need to.3) Getting full control of the property, while allowing your aunt to keep her ownership.- Have attorney draw up a contract to do this.Suggest you offer your dad some cash, now or in the near future, to motivate him to transfer his ownership to you.It may not work out, but you will learn a lot either way!

The primary thing you're going to run into is whether or not a lender, at purchase of the property, will allow there to be a secondary lien on the property.

Preforeclosure, Pre-Probate, tax liens are  OK -- however most seasoned and newbie investors are calling these leads as well and making offers.   

(1) File FiFa with the courts(2) Find assets (car etc.) to file lien.

I recommend that you look at Notice of Defaults, Vacants, Tax Liens or Probate. 

#2...not the zoning, although that can be important too, but the actual property code in the Florida statutes about tax liens and the process.

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 have made my own list of leads as well with some properties that I find vacant, probate, tax lien. but have only helped an out of state realtor on a deal a yr ago. and 2025 I would like to have the right people to go to with questions and or properties when I talk/find home owners that are willing to get rid of the property as well. 

Because of the nature of a tax lien, it would be difficult to obtain financing from a commercial lender secured by the tax lien itself.
