I believe impaired self-confidence can adversely affect success not only in real estate investing but success in general. 

Retired and mobility impaired would have been a more accurate description.I don't think we'd take any legal action yet, but I will tell my sister to not enter the house if he isn't fully clothed.

Municipal regulators will always look to the titled entity for impairment corrections because ultimately its the owner that has the most to gain/loss should conditions present dictate changes.In the situation story, and in most instances in the NYC marketplace, landlords will need to incorporate new language into their rental/lease contracts that prohibit and AirBnB use, and furthermore pass on the financial liability for any breach to the tenant.In no way shape or form should the temporary on demand tenancy have any liability for building or use infractions resulting from their rental. 

., if you purchase a unit from acwholesalers.com, do you have any problem with the warranty being impaired?

@Nick L. is correct about the valuation problem, although I'd say they are undervalued because they are impaired by non-conforming financing.

That's a good basis to impair properties against each other as most other costs are consistent.

Almost $165 billion of mortgages for skyscrapers, shopping malls and hotels are due this year.While financial-market conditions “have improved considerably in recent months,†the markets for ABS and CMBS “are still impaired and seem likely to remain so for some time,†the Fed and Treasury said.The central bank said it doesn’t intend to make other types of collateral eligible for the program, indicating officials rejected adding residential mortgage-backed securities after considering such a move for several months.

You will have to take an impairment if your model sucks once your reversion cash flow is realized.

I'm not one to avoid people in general but if I were I'd avoid  those who think or call others ignorant.It's way too strong and  offensive  a word for the sentiment you are trying to express , in fact some may feel the use of that word in the specific context you  applied exhibits it ig.....( oops I nearly  did it myself)... impaired judgement.

See http://www.biggerpockets.com/blogs/3/blog_posts/39...the CFPB has the final say on owner financing.Creative Financing is useful for not just credit impaired investors; there are restrictions even with good credit on US Govt backed loans such as FHA 203B http://portal.hud.gov/hudportal/HUD?
