There arn't and lower interest rate FHA loans to assume on multifamily which would put you in todays higher market rates.

The information I am looking for would be the standard points an investor might want to know, including average home prices, median income, crime rates, real estate forecasts etc. 

The HEI/HEA is not feasible because of the percentages most companies are wanting to take (some are over 50% of the appreciation from the date of the HEA).The biggest question is that we'd be losing our 2.875% rate, which will be paid off in 15 yrs.

I would like a fee schedule where I would pay per call if possible, as opposed to a monthly rate since most things I will take care of myself, except those items listed above since I’m not in the area. 

Ask for examples of how they have helped other investors find profitable deals and navigate challenges.Discuss key investment metrics such as cap rates, cash-on-cash return, and ROI.

You need to do the math carefully and make sure it cash flows under that new loan (70%ARV) at your new rate.  

Strategies might also include, get the seller to buy down your rate, find a less expensive property, analyze more properties, look out of the LA area, or even out of state.

Is it better to do a smaller down payment compared to 20% to save on interest rates and then take a lump sum to recast the mortgage?

Is today's market and interest rates worth me utilizing an FHA loan for what some people have referred to as "house hacking" and beginning an investor path that way?

They average to about $60-70/mo of expense that I would not have had, assuming a market rate tenant would have stayed the same period of time.
