I told this neighbor that the contractor is just blowing smoke, but my neighbor says this guy seems to be nice guy and giving him a few bucks won't hurt, so I made a bet with my neighbor, gave him $80 to give this contractor, but I bet this guy would come in a few hours, take the money, and disappears for another week.What happened?

I would be interested to see what MI and OH notes are doing these days.back in the day the bigger players would not even bid on those notes  :)  I don't play in that sand box other than with commercial banks that call me on one off's.. and its has to be a smoking deal for me to knowingly go into a bad situation up front.. that's why I recommend talking to those that do it for a living have their systems in place etc etc.. in my mind small mom and pop investors take a huge risk trying to play the NPN game .. and would be better off finding nice performing notes.. but that's me.

Bedrooms shall comply with the applicable provisions of this code including, but not limited to, the light, ventilation, room area, ceiling height and room width requirements of this chapter; the plumbing facilities and water-heating facilities requirements of Chapter 5; the heating facilities and electrical receptacle requirements of Chapter 6; and the smoke detector and emergency escape requirements of Chapter 7.702.4 Emergency escape openings.

The smoking deals I just had to cover the carrying costs.

Think if you posted stating you had a duplex in Ohio and were looking for an investor to partner with, versus a post stating you have a multifamily project in Ohio and you're looking for an investor, it's the same $80k duplex just smoke and mirrors taught by guru's, these are simply tactics being sold during weekend seminars, books, and Podcast.

Holy smokes!!!! 

More than one FU response because of my no smoking & no pets policy.

When you replace them the new ones likely wont' match exactly, age, smoke and whatever will have stained the original.
