Need help with wholesale lead I have in Florida

I was door knocking and found a 2100 sq ft 4 bedroom home that will sell for around $550k but is not listed. The house can be rented for $3000/mo, and the back garage can be converted into air b&b for $2000/mo additional income for a total of $5000/mo.

The renovation to reach this rental income was estimated to be about $25,000 by my general contractor/real estate investor in the area.

If you have experience in Miami Dade county wholesaling leads please let me know if you have a contract and/or can help me wholesale this lead.
