Being conscious of what is being flushed down and staying on top of clean outs will help things out for the long term.  

Drive for dollars and cold call/direct mail those leads if you are budget conscious. 

Additionally, as the world becomes more environmentally conscious, there will be increasing demand for homes that are sustainable, energy-efficient, and designed to reduce their impact on the environment. 

Just make sure to clean everything up nice and make a clear description of your place and requirements to secure the place (being conscious of fair housing and not to discriminate). 

It's all about vigilance, being trained and prepared, knowing the risks and consciously accepting them. 

I spent 10yrs and 10months on active duty before I got out, but I did it consciously.

Certainly there is also a market for environmentally conscious renters too.

Plus it makes you look professional to your owners and tenants so you can blow your competition out of the water.My second bit of advice would be to be very conscious of who you place in your properties. 

Sounds like you may be more risk-conscious at this time, wanting to pay off some properties instead of leveraging all of that money.

Is it not reasonable that these improvements attract quality tenants and that health-conscious tenants/buyers would consider this a plus and be willing to pay a little extra?
