Another technique might be the agent calling or emailing the agents for the target properties and asking about flexibility on price. 

You see Rina, Rolfe spent three days painting a picture of:1 - The perfect business (high gross margins, high barriers to future competition (quasi local monopolies), increasing demand).2 - Claimed that this perfect business counterintuitively sells for a big discount to its true value - and painted a plausible dual reason for it:a - the stigma premium - mobile homes are yucky and embarassing, therefore demand for them is lower than would be expectedb - the current set of owners of this asset class (mom and pop) are so stupid and lazy that they have priced the rents of the asset class lower than they should be compared to apartments.3 - He then masterfully executed the classic sales technique of creating a sense of urgency - saying that the current fragmentation and irrational discount-to-value of this asset class (mobile home parks) will soon expire because "mom and pop" are dying off, and will be selling out to professional investors with huge pools of capital.4 - He claimed that when this de-fragmentation occurs (the next 10 years) the discount-to-value will disappear and that the real value of the rents of mobile homes will finally be extracted through inevitable professional management.Item number 4, Rolfe must know, makes any experienced investor salivate - it's like cat nip.

I know that the price tag isn't everything on a property, and you must "make a deal", which I plan to do no matter what by employing all the techniques of marketing, real estate meetings, networking, etc. 

It seems the most popular technique is to go through the county's office.

Any techniques you have to share!

I’m able to see what techniques worked and didn’t work.

Overwhelmed, scared, confused...yet, motivated, excited, willing to learn and apply tools and techniques by proven multifamily investors.  

Would anyone mind sharing any free-to-use and reasonably reliable technique to estimate the rent of a rental property?
