$250 for desk, nice chair, 2 bookshelves and all i needed was two strapping young men to haul it in and a screwdriver (and some chewing gum and a paper clip).

The only way a home would have asbestos is that someone found and used some old asbestos tile mastic, other old building material or some such remote chance scenario.

The sub used a 1/4-in. square notch to sparingly spread budget mortar for 18-inch square tiles and dropped them in, because r'aal professionals don't need no stinkin' backbuttering and swirling spreading is good enough for mastic, so it should be good enough for mortar.

I've had luck in shirley/mastic area.  

InBuy a pack of gum each month

But the carpet was not steam cleaned ...full of stains and bubble gums everywhere... the lawn was now even maintained...full of weeds...grass almost dead... so we had to put some fine for carpet and lawn...And also for the lease breakage...

Your mom can't do this and it is not fair to her, unless 50k is like buying a stick of gum.

"I know and trust the companies".On another note, with metal duct, what gauge of metal have they included; are they using long turn fittings with turning vanes; are they using tape, mastic or Aeroseal on the joints; what is the R-value of the insulation (on metal or the flex); have they performed a Manual J and Manual D; have they included dedicated returns to each room or just one central one?

Yes, my investment is here in Mastic Beach, it is a tricky area to be an serious investor, but the rewards can pay off if you know what your doing.  

I used the coat hanger and a piece of gum to fish out all the quarters to buy beer.
