I am looking at starting a company with an initial investment of $50 and the option to deposit as much as you would like at anytime with no minimums and an option for debit/credit card linked account for round up automatic transfers.

It is 2019, most, if not all, of our potential clients have credit and debit options open to them.

It's called "mark to market" accounting and they would be able to record a sale of the house for 280, credit 60k for the escrow, then record the 280k mortgage as a debit of $480k. 

I just came across a lien note with the following language “Prepayments will be applied to installments on the last maturing principal, and interest on that prepaid principal will immediately cease to accrue.”I had a few people look at this and got 2 different interpretations so casting a wider net for consensus and feedback.

You can setup your business account and it will allow tenants to pay through ACH or credit/debit card.Bank-to-Bank:  Zelle works great with the major banking brands but if you use a more local bank then it might not be available. 

Your tenants can only pay through ACH or credit/debit cards typically. 

I also deposited the rent into a different bank than my usual and shredded the debit card so I couldn't spend the money except with great effort.

So I'm looking for ideas where I could really boost my earnings by being even more hands on and/or taking on more debit, another area, type of property, ect.  

There are hard closing costs as well as prepaids/escrows.

My spouse and I set up solo 401K trust accounts at a brokerage firm that also provided me with a check book and a debit card for my individual account.
