We wanted to make sure our home was very energy efficient, which meant strategically choosing which trees we kept in place, and then angling the house right so that the trees provided shade in the summer, but that those trees didn't pose a risk in the occasional winter storms (trees grow and root based on prevailing winds, so once you cut a few out and change the air-flow, they can become more susceptible to blowing over).

actually it seems to be taking more than an hour to dry completely. probably depends on the ink, air temperature/humidity. if i was in a hurry, i could probably carefully cover the ink with some clear packing tape.

I'm focused on family rentals, so I'm not sure what you are thinking specifically (Air BnB? 

Brad,The home needs the kitchen rearranged with backdoor moved to another room, full and half bath update, new windows, carpet, paint, landscaping, door replacements, and a air conditioner.

If you're in the Air Force, the portal has a link to Universal class where you can take courses on property management and business.

I think my houses are nice, but very basic (refinished hardwood floors, central heat & air, white appliances, sometimes but not always new fixtures, laminate counters), and my rents edge just above average.

have not had to do this, but why not try and call an appliance repair place or air conditioning contractor and see if they can remove the refrigerant ?

Air-born asbestos is very dangerous/ toxic and its not safe to have people in the home while this work is being done. 

I have a 2 bedroom 1 bath  , 800 sq foot bungalow  for $35k that I am rehabbing to rent and eventually sell in 10 years (ARV $63k)Should I go with central heat and Air, as it would payoff for a resale later or a less expensive route such as a PTAC unit.
