Simple questions are asked, but the answers are only easy if you know how to answer.  

Simple google search will get you there and they're actually helpful.

We are experienced investors and know how to try the simple things, like the auditor's web site, on-line records, tax records, white pages, etc. 

I learned A LOT living in a simple 2 family for example the importance of good tenant relations.

Our plan is to hold long-term (10+ years), with a primary focus on positive monthly cash flow and equity capture through strategic renovations (targeting a 10% to 15% increase in equity above the cost basis), with a secondary focus on properties that are likely to appreciate in value over the investment hold period and tax benefits derived from investment real estate.Right now, we are trying to identify real estate brokers/agents in the DFW area that specialize in 2-4 unit buildings with a real estate investor mindset.

Simple answer is they just base it on per square feet and construction quality level.

I started this project hoping i could efficiently review the most amount of properties in order to maximize the potential investment options to bid at auction....this is what I have so far.First thing i did was to create the listings, I matched the properties been auctioned with their corresponding pics and the property specs (rooms, size, floors etc.).Second, for each property I automated the data collection process from public records and created a report with: Foreclosure info, owner info, taxes data, liens including mortgages , satisfaction of mortgages,  assigments, violations and permits and court dockets.This data is updated daily to capture new filings (specially the dockets to capture bk and motions to cancel sales)Now that i have the data i can apply my personal "preferences" to go through the report and in a few minutes discard  properties that have certain attributes I "dislike". 

@Jonathan R McLaughlin That is a super straight-forward response and will make my next evaluation pretty simple.

Sounds simple enough. 

As for gain, is it as simple as bought for $150K sell for $250K?
