I will say I have a method for a free $250 but you need 1k to do it. Also not without risk. I did $1000 deposit on underdog to get $1000 match. Your money is locked once you do this. You then pick two lines that are guaranteed to only have two outcomes on each ex: curry over/under 21.5, 3.5 rebounds etc. statistically you are guaranteed to lose 25% when you bet all outcomes.
You gotta get a crappy job or start hustling DoorDash, uber, grubhub, etc to at least get your rent paid. Do not take loans if you can avoid it. Maybe sell some of your stuff. Otherwise you’re gonna be living on someone else’s couch, your car, or (if possible) move back in with parents. Taking debt is the worst thing you can do in this situation
Also if sports betting is legal in your state, abusing the bonus bets to bet on both outcomes of a game to essentially make free money. I made close to 2k doing this when I was broke. Again not without risk as they could lock your account but significantly lower risk than the underdog method. Check terms on bonus bets to see if your deposit has to be played through.
