In my area I have built an initial list of about 20k potential property owners (from an online list company) and will start off targeting a 1k list. 

It is pretty rare to buy, fix, and flip to a new retail buyer in less than 3 months.

You should connect with a realtor and get access to the MLS.Real estate listings on zillow, trulia, realtor will not be as reliable as what is found on the MLS(or equivalent).Properties on the online sites may have already been sold.Furthermore, properties just recently listed on the MLS may not show up on the online sites until after a couple of days.

A lot of these numbers Brandon says to just do a combination of knowledge, quick online research and rough estimate:Purchase price: $259,900 (this is pretty simple but I noticed in other BP's videos they will change the purchase price, either lower or higher, is there rhyme/reason to this?)

I really want to start learning more aggressively but can't find a good colleges to go to online that focuses souly on REI.

I bought an apartment off an online auction for $53,500 (I used cash). 

A few months back, my partner and I bought two properties at an online auction after having success with our first property that we flipped.

If you’re interested in paying retail I can give you a list.

Is there an online interface for tenants/owners?

Problem is seller is asking for retail price value, about twice as much as I want to purchase for.
