@Michael Tempel,Spyderwash will set you up with equipment and a distributor that can sell machines as well.You will need wifi in each laundryroom.I looked into this for a client of ours, we didn't go with the proposal, but there is an option out there.Let me know if you need any contact info.

Is there a source online to purchase quality kitchen cabinets at a price that won't break the bank? 

As for flooring, I think I will keep the existing carpet (LR, BRs), clean them up, and install wood look like vinyl planks in the kitchen.

Currently we have this on the listReplacing interior door knobsInstall Kitchen CabinetsReplace Trims /Patch TrimsInstall drywall bathroom/tile shower surroundReplace Exterior doorsNew Door bellFix outside wooden railLet me know what you think, if i should get specialist for any of the tasks above?

Is this the water main line , or the pipes feeding the baths and kitchens ?  

The cabinets are in good condition but I’d like to change the color to give the kitchen a facelift & get a little bit more income from the unit (along with replacing floors & painting) What is the best way to refinish the cabinets while ensuring they’ll still be durable for renters?

Of course it's slightly different business model with deposits and rent and equipment damage and such.

There is no off street parking because the covered area is filled with workout equipment, non operable cars, and metal waist.

Kitchen needed help wallpaper everywhere.

Any upgrades or repairs, to kitchen appliances, in unit laundry, water heater or AC unit.
