We have published that a 384 sq ft studio in Sanford has rented around $1,200 per month long-term, and that a 1-bed vacation rental in Wells has cleared $3,000+ per month in season. Those are examples from the rental-income article, not a forecast for your lot.
Illustration only: $1,200 × 12 = $14,400 per year against The Bean starting price. The live catalog is $155,000–$408,000. Vacancy, taxes, insurance, and the loan payment are not in that division. Use financing and a consult for a real path.
