There is definitely crime in the areas as in any downtown-ish area but murder and very violent crime have significantly decreased over the last 20 years.so here's my dilemma, rents would be great in those areas versus my mortgage and I think cashflow would be high. long term I see the area moving into a somewhat B- but getting better nonetheless but TODAY I would still have to deal with the kind of people that live in these neighborhoods and they're generally lower income, lower... let's say weaker moral compasses and such. so, should I get my name on a property this year and just navigate these things as I go?

Any insight on why leases would be up, but the lease price decrease.

With bigger buildings, you typically have some kind of set layout, instead of all these cut up 1/2/3/4/5 units, decreasing repair costs/time.  

This allows you to create value (increase income and/or decrease expenses) when the market remains the same.

The decrease in profit margin?

Furthermore, industrial space will fall by about 1.3 to 7.1%, and rent availability should decrease from 0.7 to 11.2%.

The question that I have is: who thinks this will RAISE the price of my property and who thinks this will DECREASE my property's value. 

I thought about getting a multi unit, but I can't justify putting down $50-100k down in L.A. with minimal returns while decreasing my liquidity.

But if it's predicted that Cities will continue to grow as people move towards cities, then it only follows that other places may have a decrease in their population.Combine a loss of Driver type jobs, Manufacturing jobs, and a migration towards Mega Cities, and I think you get a good picture of which areas seem to be a good place to invest for the future.Combine that with Climate Change, then all of a sudden, Cities that are predicted to be Mega Cities, may have to shift to inland, since most of the Mega Cities are coastal.The point here is that there should be concern on where to invest, if only for Asset protection. 

You also don't want to hold too long of course because the lower balance decreases the value.
