First off, anything coming from a guru's mouth should be taken with a grain of salt and secondly, if it were that easy, they would be making the easy millions doing that very thing, not teaching it.

Due to the gout lines it's harder to seal the bottom edge.

They may still be a need for auxiliary heat (electric baseboards) in bedrooms - or all areas - either from a regulatory or practical position.Another thing to consider are improvements to the building envelope - air sealing, insulation, windows, doors, etc - will have a bigger impact on building performance than changing out the type of HVAC.We have removed a central HVAC in two smaller buildings (4 & 6 units) and replaced it with ductless split and auxiliary electric baseboard and are pleased with the results.  

Regardless of the letters you print I suggest paying someone to address, stuff, stamp and seal the letters.

Employment will continue to rise.Inflation fueled by debt will be the greatest threat by end of the year, but I think we've seen this year that it's a delayed risk which the stock market/mortgage rates can overlook in the short run.In Atlanta, I think we'll see rents continue to rise sharply while new construction continues to spin up and non-investor buyers come back into the market.I think multi-national companies, domestic consumer goods/services, and foreign markets will outperform this year.Take this with a grain of salt.

Maybe those transitions are not sealed up good.  

Caveat: I'm pretty new, so take what I say with a few grains of salt, as I'm relying primarily on what is learned on here and the podcast.

@Lisa PerezWe are frequently criticized for spending too much on our renovations - energy efficiency is core to our operating beliefs, so we frequently spend a little more time improving "out-of-sight" things (air sealing, insulation, LED lighting, ventilation, etc.) then many of our competitors.Similar to the sentiment you expressed, I am also a firm believer that our properties should be in a condition where I would be willing to live there with my family before I could ask someone else to do the same.  

Make sure it is sealed properly to prevent water intrusion.

And to rub salt in the wound the seller already gave back all their deposits.
