Nail holes in cabinet woodwork or doors.

Anyway, the townhouses were brand new when we moved in so the house has been settling causing paint cracks in the corners of several walls and it has caused the baseboard woodwork to separate and crack in several places.

My goal - develop enough cash flow in 5 to 8 years through CRE to be able to "retire" from engineering and do what I really love, woodworking.

But if you tell us who you're dealing with, some others might come out of the woodwork and perhaps be of some assistance. 

You might want to ask what type of birds...large macaws destroy wood work and drywall if they can reach it....and Conures are ear-splittingly loud...

We paid cash for the initial purchase and funded the entire renovation with money made from my woodworking business.

You'd have to enjoy woodworking.

The other houses I skipped through have crown mounding, lots of woodwork, etc.

Thanks Marc, the lease actually says:"Tenant, without the prior written permission of the Landlord/Agent, will not remodel or make any structural changes, alterations, or additions to the Premises; will not wallpaper, paint or decorate; will not install, attach, remove or exchange appliances or equipment, such as air conditioning, heating, refrigerator or cooking units, will not drive nails or other devies into the walls or woodwork...The installation of television/radio dishes, antennae or cables, while not restricted by Landlord/Agent, as required by the FCC Telecommunications Act, as amended, shall not be installed, by Tenant, in any manner as to cause damage to the property. 

We have found that window treatments in our priced homes are a personal thing and I don't want to put any necessary holes in the original woodwork, as most of our homes are in the older areas of Memphis.
