Hello BP Members,I'm proud to say that I have finally closed on my first deal and I am eager to embark in this journey of Real Estate Investing.After closing on this 4-Plex I ordered an HVAC Inspection because one tenant started to see leakage from the ceiling and another complained that one of their bedroom was getting poor air flow.The HVAC inspection result showed that I would need a complete HVAC replacement which will cost me close to $40K (10K/door), an expense I did not expect to incur.

If there's been a lot more cooking due to COVID.Really, a lot also depends on how the washing machine drains its water into this sink.My main worry here was that there might be a CRACK in the stack that caused the leakage, because that would take some expensive demo work to pinpoint to repair.

I will order HERs test checking for leakage.

I have Honeywell 9000 wifi thermostats, Rheem wifi water heater with leakage sensor.
