Anything that constitutes a major inconvenience to the tenant, such that a reasonable court would find one negligent for not addressing quickly, constitutes an urgent maintenance need.Example of the former: leaking water, gas, exposed live electrical wires, smoking in electrical panel, dangerous leaning tree, etc.Example of the latter: poor heat performance of heating system; clogged gutters overflowing causing basement dampness; etc. 

The foreclosure and tax deed auction is the first Tuesday of every month 10:00 am sharp on the counties court house steps.

A lot of investors and wannabe flippers, don't realize the complexities and pit falls of second grade work by lousy contractors with undefined scopes of work.I always tell my prospective clients, that the place to save on a project is not on the cheapest Architect or Contractor.
