Personally I see the thin masks or neck sleeves everyone wears as pointless.

Have considered mini-splits(continuing maintenance is a turn-off), ptac(size of exterior sleeve is a turn-off), and vtac(just started looking into this one).Wanting to maintain the exterior appearance, use a system that will last with least amount of maintenance, and make sense for profit as we intend on holding this building long term.

Sleeves are a good idea if there are no roots, breaks in the lines, etc. 3.

If you roll up your sleeves you can take care of most other things within budget.

Would like to find a hungry agent, who's going to role up their sleeves and market and sell the property.Willing to sell direct, if a buyer came direct. 

Very rare but an ace up your sleeve once you find one.

Unfortunately, most of what got the market in trouble is back again now, arguably exponentially worse and with some new tricks up their sleeves.

other wise this is a roll up your sleeves and jump into the deep end if your going to makethose types of properties run efficiently and profitably.

@Jose Lopez Do you have any construction skills, office backend skills, or are you just willing to roll your sleeves up and learn?
