@Nadir M. Unfortunately it’s a learning lesson and you’ll never make this mistake again. Never let a tenant move in by paying online. Most processors take 1-3 business days to pull funds out of an account so you won’t know for a while if they had the money to begin with. Always ask for security deposit and a full month’s rent in a cashier check or money order. No exceptions! We made plenty of mistakes when we were first learning and self managing but we have learned many hard lessons. Professionally managing is much different. When I started self managing I thought paying a property manager was a waste of money but after all I’ve seen professionally managing the last few years, a property manager is 100% worth the money.
Depending on your state and laws, if she doesn’t come up with the cashiers check in the next 24 hours I’d post a notice and be super firm with eviction proceedings. Giving any flexibility here will just be a waste of time and money. Hire a lawyer for the eviction. The slightest mistake doing it yourself could cost you to lose and it isn’t worth it in my opinion.
Best of luck!!!
