(Last time around, it was adding mezz debt to your permanent debt to raise the LTV and get better returns on equity.  

I'm not too concerned since I believe there are deals in all markets, and I'm a long-term buy and hold investor, so it doesn't impact me.    

Generally a recession does not impact most rental owners too hard since a recession will drive more renters into the market.

Multiple Section (Double/Triple) Mobile Home attached to permanent foundation.

One implies impact on current decisions vs one implies a statement about what will come.I'd be curious about your view on these 2 statements as I pick up a general negative vibe towards forward looking stuff. 

What type of impact do you thing section 8 neighbors would have on my non-section 8 rental?

The house was in such bad shape that even though competition was pushing up sales prices of homes in the area this one wasn't impacted.

This is why I sometimes argue with other investors passionatly about their behaviour when it is 100% profit driven and IMO without consideration of the impact on the public - I don't want to be seen as a predator, who takes advantage of people that are what some call highly motivated (= they have no choice); I run a for-profit business, but we should not put dollars and profit over our social responsibilities - and in the end out public image.

Maybe look at subdividing lots out and put permanent homes on foundations. 

HELOC's are not good products for long term, permanent types of financing.
