@Joe S.

If you're lucky and the attic is brutally hot, the ducts will have a harder time cooling the air down enough, so you'll have less condensation than in your "well ventilated" crawlspace, but that's still not a good bet to take.It is one thing to see regular joe schmoes not understand this, but it is absolutely infuriating to see that inspector gave literally the opposite of the correct diagnoses.You can choose to waste obscene amounts of money moving all your ductwork. 

Supply chain and labor problems aren't going anywhere for a while.

I hope everyone is enjoying the Labor Day weekend (or did if you are reading this after Monday). 

materials and labor increased so much that it will be very hard to make the numbers work especially with all the track builders there.

Contact Joe Prillaman in Wilmington.

(I can't build the track for the sale price)Their business model, in my opinion, is too labor intensive with high overhead.

Quote from @Joe Norman: You have tenants who you can't speak to, they don't use email, and you're out of state...and you still want to self manage?

We replaced 2 units last year that we tried to replace only heat and ended up doubling labor because exactly what they cautioned you on happened, both had start up issues.  

I have a note pad on my iPhone of materials $ and labor $.
