If you are showing monthly deposits of the same amount each month that are in the amount of a rent, you would need to show where that money was coming from and going to, as in which address it applied to.

There are several types of fees on Airbnb specifically: -Airbnb service fee, cleaning fee, extra guest fee, pet fee, security deposit, VAT (if applicable), and local taxes. 

In most situations the tenant is 100% responsible for the initial security deposit payment, and any recurring utility charges. 

I accepted a prospective tenant's lease and deposit after doing due diligence.

Our average online rating is 3.5/5, which is 60% higher than the 2.2 star average of traditional property managers.Sometimes we need to make a tough decision in favor of one side of the landlord-renter transaction and at a negative impact to the other side (i.e. deducting security deposits).

I would charge it now so that it doesn't need to come off the deposit at the end leaving you with more deposit for any other damages.

It's also wise to check references from previous landlords to understand their payment history and behavior as a tenant.Once all the information checks out, you can proceed to signing the lease and collecting the security deposit and first month’s rent.Good Luck!

1) Smart, successful value adds that would allow you to extract sweat equity.  2) patience to save up the deposit via you income.  

In my experience it helps keep pre-applicants organized and is an actual sight with a google-able name so it doesn't seem as scammy.The background check and credit fee is $30 paid by the prospective tenant but I always tell people applying for my units ahead of time what my credit and background requirements are and that if they pass those qualifications (plus the reference checks) and sign + pay the deposit that I will reimburse them the application fee.

You also should have dealt with the security deposit which belonged to BOTH of them at the time.
