Interested in more active bidding.

Recently caught the REI bug and lenders I've talked to will approve $40K-50K max due to the age of our accounts and lack of activity opening new lines of credit. 

Pinnacle investments, smartand, Memphis invest, turnkey properties (formerly Memphis turnkey), Ohio Cash flow, These are just a few that are active on BP.

i keep reading different articles about active and passive income, you say this will be passive, what would constitute it as active?

Quick search on the forums will indicate that all 4 areas you've mentioned have solid activity (buy and sell). 

Because a house purchase is a significant investment in one's life, it is worth your while in having a title attorney to ensure clear title and smooth closing, along with a good inspector to assess the investment property's condition, a good realtor that will protect you with the contract, and, of course, a good mortgage broker if you need financing for your deal.   

Just looking to start being active on BP and learn/contribute as much as I can. 

Vlad,As was mentioned before, do your homework to understand how the LOC works and assess your longer term goals.The LOC can be useful (I just opened one myself) to find deals.

SMLLL doesn’t file a return, the activity gets reported in your personal return.

Slow your life down and move from active to passive.
