South FL: tax certificate -> foreclosure -> victory?

[Scott Rosslow]

In South Florida my wife owns a Townhouse in a small HOA 4 units. Names are changed for privacy.

1. Wife owns unit one
2. Fish owns units two and three
3. Gold's estate owns unit four

My understanding is over a year ago Gold passed away over a year ago. Her son in an email to the HOA said he has turned over the property to the reverse mortgage company. I tried calling the company to followup on the lead and the reverse mortgage company couldn't locate it in the records. At this point I have waited and checked ever so often to see if new court records have been filed on the property. I can't find any evidence of foreclosure.

In the meantime Gold's other son has since been squatting in the unit who I think was not allowed back, by the HOA, into the property (drug abuse). I also know the HOA has filed a lien on the property for the HOA fees.

Today I looked through the taxes and saw someone bought the 2018 tax certificate.

My idea from here is to reach out to the 2018 certificate owner and try to buy the certificate. After I am allowed by the certificate I would try to foreclose on the unit. I figure the worst case scenario is I am out some money paying for the certificate, best case I win the tax deed auction. Anyone know of any pit falls or have other ideas on how to acquire the property?
