I’ve gotten to where we have multiple doors at the same monthly rate so I need to transistion into an app to help me manage and identify who paid rent.I have a few tenants that are “technically challenged” and I’m anticipating some challenges with getting them on board to use a payment app.Any suggestions for the simplest rental payment apps (from a tenant perspective)?

I would stay with the simplest and leaset expensive.

@Christopher FreemanAccount Closed has the simplest solution.

The simplest way of putting it is that you missed the boat!

@Brent Watanabe in my opinion, the property manager is the key ingredient in a successful out of state investment recipe--they already have a network of contractors, handyman, know how to vet them and negotiate pricing and plus they have access to deals--many times clients are selling or changing up their portfolios, and you have to be a broker to be a PM. 

the extension is no more than a foot and the external wall is one of the simplest things to do.

I'd much rather that large hot with 3 creams from McDonalds.My bet (and I reserve the right to be wrong) is that the most important ingredient in a gourmet shop is marketing. 

It's about the simplest SFR I could find, with minimal up front costs, section 8 tenants in place until the end of the year and it's a brick house!

The calculator is easy to analyze and plug in the numbers if you were renting out both units, but what would be the easiest and simplest way to analyze a deal accounting me living in one side?

The simplest way is to just write a flat fee for water / sewer into the lease as a line item.
