I see you state you are from Escondido. That is our (H3 Properties) area of expertise on multi-family (duplex through quad) BRRR residences.
I believe we are better at estimating the price on those multi-family homes than any realtor I have yet to encounter. Why? Because we have personally seen everyone that was not priced too high for the market range, kept track of what they sold for, and mentally know about how long they took to sell. In addition, we own quite a few properties and do regular rental analysis. I have yet to encounter an Escondido realtor that has seen more than a few of the multi family properties. I have heard from realtors significantly off rental prices (usually they are significantly lower than market which is good to let them continue to have their ignorance).
You do not indicate where you are looking to invest or what type of REI you intend (BRRR, Flip, whole sale, etc.). However if you are considering a mulit-family (duplex through quad) in Escondido for BRRR I would be willing to tell you what I think of the price point.
Also if you are considering in our area of expertise (Escondido multiplexes) do not use list price to obtain price reference (not even as a starting point). There is a huge difference between the listing price for these properties and the selling price.
Final recommendation: Read up on capital expenses before placing any offer. So far on our units, cap expense is much higher than maintenance and vacancies together. Southern Cal has high labor cost; cap expense here will be higher than almost anywhere else. If self managed maybe use 5% each for maintenance and vacancy (total for both 10%), and $250 to $300 per unit per month (maybe 15%) for cap expense. This would imply to have any positive cash flow you need rent to be at least 25% above Mortgage including escrow. Also if not self managed there is the management fee but I also increase both the maintenance and vacancy percentage (no one manages your money more carefully than you but it takes time to manage properties).
Good luck
