G'Day Matt,You can only do so much with online research.IMO the online stats and demographics often times don't paint the correct picture.This especially tends to be the case for tertiary markets.Finding folks on the ground that "live and breath" the market is your key to success.Those folks on the ground are the one's that bring the "online stats and demographics" to life per se.They will know more accurately what's going on in their local market pretty much on a daily basis.I've always said that you can research online and find a market that has the best growth and cashflow potential.Find a property for a great price and on a great street and in a great area.But if your property manager or contractor are incompetent or cheats.You will loose money.So start with finding the right people first before finding the right market or deal.Just my opinion.Thanks

Maybe you can convince everyone involved to convert to a community owned system, with a shared maintenance agreement, reserve funds,Just need to find the smoothest path forward to needed upgrades like an above ground cistern, pumps, backup generator, better filters, or whatever to make the system function 100% of the time$1500 is minimal, spend it if that's the way forward.

I’m unsure if changing out the filter is required even if next people don’t want to spend money on replacing the filters. 

I use many different filters but typically start with the basics of out of state owners who have owned for a while.

There are so many so be sure to filter by your location. 4) Review Dave Meyer’s The State of Real Estate Investing Report 2024 (in your resource page as a member of BiggerPockets!)

A company comes out twice a year and inspects the AC and replaces the filter (very important if in a high temperature area), inspects the plumbing and electrical, and provides feedback regarding any potential issues.
