Understand true costs to maintain a home2.

@Ori Skloot  If you are paying your employees $ 27 an hour , with withholdings , workmans comp , and the other related costs , they are costing you around  $ 38.00 to $ 42.00 an hour The true cost of your labor was closer to the $ 9000 mark . 

TRUE!

@Gisell GarciaI use zelle and deposit only cards.

True?

Highly recommend you have stripe with rental agreement where you collect identification, selfie, credit card info, and e-signature.

Oh so true.

2.For purchases made on a credit card, is it best to use separate cards, or are there good methods for tracking expenses by property?

I have been told it is about 3% higher in general for an out of country investor, is this true? 

That is true, I disregarded the advantages of the quad having lower operational costs.
