I finally decided I will visit each door once a month to change filters, to check for leaks under each sink, to flush the water heater T&P valves, to exercise each shutoff valve inside, and to put bleach down the air con condensate line.My biggest stress came last month in dealing with hurricane Irma as it approach south Florida. 

The are handler needs to match up with the condenser.

When the condenser fails later on, you could simply have them flush the system and change the flow orifice of the evaporator when they change the condenser.

Depending on where the house is it is not uncommon to have some moisture in a raised foundation, as the temperature changes you may see some condensation, that is why there are usually some vents around the base of the foundation.

Yeah on mine I ended up just going with a traditional furnace and condenser setup because it wasn't much more than the mini split to do so. 

There could be condensation on the door.

Negotiated price down based on future renovations in two units (updating cabinets, floors, countertops, and condensers).

Prior to closing I had a home inspection done on 9/13 and it came back with minor issues such as 1) hole in siding near AC condenser needs to be sealed, 2) GFI outlet at rear of house will not test 3) AC condenser needs cleaning 4) leak noted under kitchen sink 5) no door return installed on front of security door and 5) could not enter second bedroom at time of inspection, inspector was told occupant had Covid (a convenient excuse I'm sure).

had a fellow investor tell me his 2 yr old a/c condenser was icing up & asked me to help check it out.

No, that includes the "outside" unit (compressor and condenser) and "inside" (evaporator coil).
