Natural gas is cleaner, easier when renting or selling and requires less space.

Most importantly you need a great cleaner and a handyman on speed dial.

The other way depends on how fast we can get cleaners arranged, get it back up on the market, shown and re-rented.

Call drain cleaner and ask them what it costs to snake a drain.

RE cleaners: ask around locally to other owners.

This industry is full of surprises and you did well to extend the benefit of the doubt to the landlord (they probably did not intend to give you such a dirty place and it does stink for all parties involved when anyone cheats and lies to another, like when the cleaners and make-ready teams do this). 

We are gearing up to purchase another property in the next year or two and are debating....do another one in the same area, as we already have cleaners/contractors/services that we trust?

I schedule my cleaner in between stays, have handymen as needed, locksmiths, etc.

It’s cleaner on your Title chain and saves you one closing if you go through with a full closing to potentially keep your Title Insurance, etc.As a new LLC it will be tough.

Its cleaner if you do it when starting the LLC, but even later is basically capitalizing your LLC or an owner contribution.
