Hi Andrew, there's so much information out there about construction and updating homes to flip, so I'll try and condense.

I had a tenant where we had the hvac unit in attic leak as the condensate was blocked.

Unless KWs are sky high in your area, then a traditional FAU with exterior condenser.

So electric water heater, electric furnace, electric condenser AC, electric stove, washer dryer dishwasher...It is 1000SQFT home.

Start with wrapping the duct that's condensing. 

If they are significantly more it could create a spot for condensation to drip.

The main issue is that the interior AC unit is old...installed in 1996 while the condenser outside was installed in 2017.

This is allowing my company to condense twice the people in the same space.

https://drive.google.com/file/...Hey Omer, I didn't see anything here that would make me run away in terror, although I would have an electrician take a closer look at those rusted breakers and also have an HVAC pro deliver a quote for installing a drip pan and securing the condensate drain line.All the other items would have been observable by the naked, untrained eye (e.g., missing gutters), so I'm assuming your offer price already took them into account.

AneU_VTSiG...I already had two AC people come in to inspect it and one couldn't even diagnose what was happening (he said "it's just old") and the other one suspects it's a condenser but wasn't sure and thinks it's better to replace the whole unit.The previous owner of the house says it's only 4 years old and should be fine.
