There are hundreds of wholesaling post already. If your budget is $400 then you might have to figure out a way of producing leads that cost very little. What area of the country are you in?

I was going to use propstream but I’m not sure about the area, i don’t know how to find good markets

$400 per month or total. PropStream is my favorite tool but if $400 is your total budget I’d start driving for dollars without paying for software and then sign up once you have some cash

Basically I was gonna use the 7 day free trial to my advantage and pay the 97 a month and then do the skiptracing and cold calling and try to get the properties under contract and collect the monayyyyy

If you have a $400 budget, wholesaling is doable but you will need to commit more time. You will need to spend that $400 or resources like Propstream, a dialer, CRM.  You probably wont have enough funds to Skiptrace, so you will need to manually search numbers (searchpeoplefree.com).

Find potential sellers on Popstream -> search their numbers for free-> call -> follow up -> Close a deal -> Find a buyer using Propstream and online groups.  

It will be very time consuming and tedious, but doable if you don't give up.
