. - One building, or 2 if very close together- No student, affordable or high rise housing- Built after 1980I understand that we’re looking for a needle in the haystack given the current market conditions, but would appreciate any advice on other sources to look into!

In my example above I was thinking 10 homes that are basically about the median price range in a county, in nice condition. 

Tough to tell without knowing taxes and general condition of the property, as well as if the rents could be raised or if they're topped out for the area.  

and with sellers that are not up to speed on what the market conditions really are.Lastly there is nothing tougher in real estate than to wholesale. 

Has the 1960s property been fully renovated in last 3-5 yrs, while 2009 build is in original condition?  

I hope they are not as new as you are.It sounds disastrously if there are 6 brand new investors going into their first fix and flip deal.If it is a fix and flip, You should create some sort of entity and request a loan from a private investor or hard money lender.Conventional financing is likely out of the door with the amount of investors and the likely condition of the property.Doesn't hurt to ask a lender if they would do it.Again would be a burden handing over financials/socials/sensitive information for 6 people for a conventional loan.

Property consists of 7 single wide mobile homes (in good condition) 2bed/1 bath on 2 acres.

The best thing you can do is look at sold comps in neighborhoods of similar properties (size & location) and look at their condition.  

This might not include upgrades, remodels, additions, bootlegs, solar, view, condition and more but the information is enough on lots of residential real estate.

(Properties were in different conditions/levels of upgrades)5) In this market of high demand and low supply, it is best to get in and stake your claim to a property.
