What's the best way to save and organize digital receipts and to snapshot paper receipts?

I would discuss financials on this if you choose to come see the pre-rehab on Dec 1 (I have made a lot of money (close to 7 digits after this rehab is done in ~2 months) but due to not executing a cash out refi (due to the rate increases) my return is below my underwriting).

Quote from @Miguel Del Mazo: Thank you for the discussion @Corby Goade .I feel like we are biting off big pieces of a complex topic, and I think it would be helpful to focus on either the interests of the property owner or the MTR operator to simplify things,I think your greater objection to MTR arbitrage lies with why a property owner would want to willlingly enter into the agreement, so I will focus my reply on that.

I'm trying to automate and digitize more processes of managing long term and shortterm rentals. 

For example, in Mexico, you can put less than 40-60% down, interest rates are in the single digits and you can get 20- to 30-year mortgages (and you can't get anything shorter actually) and the right areas would fit within @Richard Foltys' criteria.

I read newspapers (Digital) in the markets I am interested in.

With the rise of digital real estate, there are now many more options available that make it easier than ever before for potential tenants and landlords to find each other.

Multifamily syndication by average expecting 15% IRR with high single digit cash flow.I am not blaming those GP, but from financial perspective, the lending aspect of it doesn't make sense.
