First time wholeseller real estate

[Batu Dogan]

The house is 5bed/3bath 1,800sqft i'd say kind a decent location, estimated value on zillow and totalview is 146k and 144k, the problem is the house is already on sale for 80k, and I've runned my numbers even if I go high on numbers, realtor cost, rehab cost investor profit and everything Its still around 80k, and they tried to sell back in 2018 for 60k but then unlisted. What you think should I do, I'm thinking to start with an offer around 50k and limit myself at 62k but how can I find an investor if they already put it for cheap

Also does anyone know about the legal stuff in FL, I haven't found anything ethical
