I also created separate bank accounts with different debit cards for each one. 

Unless you can find a prepaid service where you don't have to attach your name to it then I wouldn't mess with it.

I can also manage maintenance requests and receive payments ACH in 2 days or via debit/credit card(for a fee to user). 

The bank will give you an account and a debit card or checks and you can make draws on the account up to your credit limit for the first 10 years.  

As for your options now while your credit is suffering…private money, hard money, seller finance, prepaid PMI, assumable mortgages and sub to all come to mind.  

So if there is a default on a debt, bank reserves will be debited and the loss can be handled on that basis, but the asset itself is destroyed.This is about the most advanced finance gets. 

I want to be easy for my guests to navigate the website, book a reservation, pay with a credit/debit card, I want to collect money easily, and I want it to integrate well with Hospitable (PMS) and Turno (cleaning schedule tool). 

i think a decent SF will cost 150k.and with 5% down n closing cost and pre-paid amount it will be way nore than that.

Originally posted by @Paul Weisbaum:This may be controversial - but I let them pay me every week instead of once a month and require automated debits from their account.

Usually rents that are paid to the original owner / Seller are collected prior to closing, the closer has a document Assumption and Assignment of leases,, this assigns your lease to new owner, and rents are prorated between buyer and seller at closing if it's mid month.. a debit to seller, a credit to buyer, and security deposits with interest are credited to buyer at closing.
