@Sylwia Leczycka I don't know if Venmo would be the way I would go, even though I never used it for rent payments, but I have used for sending money amongst friends and some other business related transactions but here are some of things I would keep in mind if Venmo is the route you decide.
1. Tenants can potentially send it to the wrong recipient first time around, and once it's confirmed then there's no getting that money back. According to the tenant they will see it as they paid rent. Landlord would see it as rent is late. Potential conflict.
2. Processing times vary with Venmo. It can potentially take up to 3 business days for the deposit to hit your bank account. This could also cause the payment to be considered late, even though the Tenant initiated the payment on the due date. Again potential conflict.
3. For businesses Venmo charges 3% processing fee. Now if you don't declare it as rent payments the fee can be avoided but if Venmo found out then that would be a whole different story in itself. Definitely would not recommend this.
4. Venmo allows for partial payments. So, even though you hope this doesn't happen, but if you are ever in a situation where you're trying to evict a tenant for nonpayment but then they send you as little as a $1, ok a little exaggeration here, but the point is they send you a partial payment, this could automatically put a stop on the eviction process since it would have been considered an accepted payment.
My advice would be to look into a rent payment platform. I use https://www.apartments.com/ for one of my properties and https://www.avail.co/ for another one. I need to consolidate it but haven't done so yet, so far between the 2 I like Avail better. They are both free and gets the job done, even though for Avail they have a paid option for a little more services, which I opted for and it is only $5 month. Starting out you can't go wrong with either option.
Good luck!
