Figure out everything that it takes to make the place work (appliances, cabinets, flooring, paint, faucets, toilets, HVAC, water heater, etc) and plan on replacing all of it at X years. 

The top of the kitchen cabinets had a half inch of greasy dirt.

Is that because you were doing both the projects at the same or do you always load the sames finishes (although I noticed the cabinets/countertops were different) in every house?

& that my friend is why they have Ikea :)We had a whole Ikea bedroom closet & cabinets left behind because they couldn't be bothered dismantling it.

The wood floor is in need of some repairs, so we are going to level and put in vinyl planks throughout the unit.The kitchens have solid cabinets in decent repair needing some refurbishment.  

The kitchen cabinets are at least 3 different kinds.

The streamlined version of the 203 doesn't require a consultant and you can do all kinds of cosmetic things with the proceeds.....paint, cabinets, carpet, tile......but termite damage, water restoration or a new roof would be considered "structural" and you'd need the full 203k for that purchase.

My contractor installed particleboard kitchen cabinets that have a oak doors.

It has all new SS appliances but the original laminate cabinets.

I have another rental with a washer living on borrowed time that could use a swap, so it works out.The dishwasher is a very old model and I have been thinking about replacing it as well as reworking some electrical behind it because the original receptacle junction box was behind the dishwasher, which means both the dishwasher and the disposer are plugged in behind that instead of the sink cabinet which is where I want to relocate that to.Prior to lease signing, tenant agreed to buy his own washer and dishwasher, as well as pay for the needed installation, and at the end of the lease term, I have the option to purchased his appliance if the price is agreeable to me, or he can take them with him.
