Charming St. Petersburg home with its own private guest house! Set on a corner lot at 18th Ave S and 41st St S, this property offers TWO SEPARATE HOMES: a remodeled 3 bedroom / 1 bath main house and a detached 1 bedroom / 1 bath cottage, each with its own private entrance, 4 bedrooms and 2 baths in all. Ideal for extended family or guests who want their own front door and privacy, for a home office or studio, or for living in the main house while the cottage helps with the mortgage. The cottage is currently leased at $1,500 a month, so the income is already in place if you want it, and the main house is vacant and ready for you to move right in. Both homes have been remodeled inside and are move-in ready; the roof was replaced in 2022. No HOA, no rental restrictions, and the property sits in FEMA Flood Zone X (non-evacuation), so lenders do not require flood insurance. Seller is offering a $15,000 credit to the buyer at closing. Minutes to downtown St. Petersburg, the Skyway Marina District, the Gulf beaches and I-275. Come see how much living fits on one lot.
