@Adam Belal Congrats on making a move! Several things come to mind here that I'd like to point out or just comment on. In no particular order.
Since you are using an FHA loan, make sure that the condo is on the approved list or this idea will go nowhere fast. Your lender should be able to provide a list or you can do a simple search, just make sure its up to date. Is the condo warrantable or non?
Second...who's still paying 3%..just kidding..I don't see many at 3% anymore!
Third, what makes you believe there will be a crash? Inventory is less than a month, interest rates are going up, new construction is behind about 6 years nationally. You can find 100 different opinions on this if you ask 100 people. IMO, any big correction is likely very far off in the future.
Depending on what part of town the condo is in may determine rents. Are you by UCF, Disney, Valencia or something else that would attract younger people that you would want as roommates and need a situation like that? There are tons of people out there getting rent increases of 15-20% year after year, so as long as your unit is convenient to what they need, affordable, clean and safe, $625 sounds quite reasonable.
I would also have at least one exit strategy to calm your fears if the market does something wonky. With FHA, you must live in it for at least one year. Can you airbnb it after that, can you rent it out for $1500-1800 after that year is up? You said if you can't get $500 a month for the other rooms, you are in hot water, so if you can't afford the property on your own, this may not be a good move for you. People that rent by the rooms (I'm speculating) are not going to stay forever, you will have gaps and turnover, that is part of being a landlord, accounting vacancies is generally 10%, with renting by the room, I might double that.
Probably more to dig into here, but Good luck.
