But on the other hand real estate trends change so slowly, especially migration trends.

It's data + personal preference + which way is this block trending (D+ to C or C to D+).

On the other hand, non-local lenders may offer more competitive terms or flexibility since they're not tied to specific regional trends.

Over the years, I have 1) invested heavily in education (underwriting, financing, market analysis, asset management, identifying macro/micro trends per market, etc), and 2) developed strong relationships with a network of accredited investors who are interested in diversifying and jumping into the multifamily space.

Do you have enough time in these that you can show consistent trends in expenses and vacancy rates? 

This is mainly due to the large amount of inventory and still high prices (though they are trending downwards).

Ive also noticed a big trend in private lenders originating 2nds and gap funding and whatnot.

.- Keep an eye on the local market trends.
