Multiple people in my neighborhood had issues. 

This results in multiple offer situations and bidding wars, driving prices too high to make them good investments.  

Sonja, in the Madison Wisconsin area we would never find that much of a discount - on the MLS (Multiple Listing Service). 

It does mention 'multiple possible judgements'.  

I also don't invest in the city for multiple reasons (the ED department being one of them, which would probably come into play if you are looking to do something other than buy and resell some land in the OC)I know people who have done very well on Murray Hill and the Gordon square area.

Use the roughly $50k to purchase a single unit outright, or split it up for multiple down payments and purchase a few units?

Shari Lawson Yes, it has - multiple times.

What steps can I take to ensure I'm not wasting my time and there aren't multiple liens on the property?  

I'm new to mortgage industry and I just wanted to see if anyone had a few pointers on marketing your loan programs on other blogs/websites, suggestions on how to approach brokers to keep them engaged right away, and how to assure them that being new to the industry doesn't mean you aren't reliable.

I use multiple cards for re-habs and that works well but it would be easier to have a line of credit to keep everything in one place.
