Also what specific expenses are needed to calculate regular upkeep for property? 

Once the realtor rents the place, then you should just be on regular management of the property. 

There are companies that will supply coin-operated washers & dryers, service them and split the funds with you.Confused though, you stated you have a 4-plex, but that the laundry area supports 16 total adjacent units.

And this isnt the time , with material costs up sky high and labor in short supply even the big players are having problems with supplies . 

The values are shooting up because retail people are able to pay more due to low interest rates and low supply.

But one thing it does seem would be beneficial would be to use an accountant that's familiar with every possible way to deduct your expenses now- someone who invests themselves or works with investors regularly- there may be things that qualify for expenses vs capital improvements that weren't accounted for. 

I'd figure my regular job paying what it does would allow me to cash out no problem.

@Michael Baum Yes, you are correct that regular preventative maintenance is key, as well as having a good local handyman.

If course, it would be one thing if builders could quickly scramble to increase housing supply.

Minimal duties include: obtaining monthly dues, tracking delinquencies, thorough bookkeeping, regular communications to owners of budget, hosting a website, regular maintenance on the property, and managing and vetting contractors, managing contracts and renewals, etc.
