The panels are built in the factory and I can frame and dry in the home in less than half of the time.

I got some dry ice and froze exposed section in building and replaced 1 globe valve with two ball valves of 1/4 turn nature. 

Groetsma had to pull his hair out on this issue, but he was able to get it mostly resolved.  

Remove old wall paneling and horse hair plaster underneath, and install new drywall or just paint old paneling? 

By the book I would say you need a permit but also know its not always cut and dry.

I'm always surprised when one seems to dry up, while another one suddenly starts producing leads.

IF it's not your age, it your hair, style of shirt, skin color, gender, facial hair, choice of car, tone of voice, ect... you cant appease everyone nor should you try.

Based on my experiences with the 1bed/1bath's that I currently own and the difficulty that I have getting them rented and keeping them rented I would pull my hair out trying to find 25 to 50 of these typically transient tenants. 

Many homeowners and landlords alike have converted their traditional lawns to xeriscape (xeros = dry, -scape => landscape) in recent years, both for environmental and cost savings reasons.  

The tenants that you actually want will present a little bit more elusive, because they know their own worth as tenants.Getting another $50 out of your rental is not that important compared to finding a good tenant, who does not cost you thousands and some grey hair.
