We are near the P83 district (about half a mile) so a lot of the revenue was coming from baseball tournaments and sporting events; come spring training time I think our rates could go up quite a bit.  

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. 

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?)

Like @Gregory Hiban pointed out, listening to Dave Ramsey or possibly even going to his Financial Peace training may help in this area because it's the exact type of thing he talks about.Second, the car situation is a problem because you own two cars that you can't afford and it's going to be hard to get out of them (and one that you probably can't get out of at this point). 

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.

Is there an online interface for tenants/owners?
