Quote from @Sean Quinn: My new favorite is in my signature. :)The best book I've read is "The Unofficial Guide to Real Estate Investing" by Spencer Strauss.

@Rajesh Kasturi My favorite MTR market for cash flow AND appreciation is Portland, OR. 

Not sure where you're planning to take her but here are a few of the local favorites:-Pappas on Taylor Ave (they've opened up a few new locations too)-Kocos Pub on Harford Rd in Lauraville-Faidley's Seafood in Lexington Market-Box Hill Pizzeria in Abingdon (about 45 minutes outside of Baltimore but worth the drive!)

I actually have done a lot of research on this because I love 1980s and 1990s arcade games and plan to collect my favorite 7-8 games eventually.

You need to minimize upfront expenses because 100% of your investment is at risk and lost if the lot is not buildable.My favorite strategy is to locate the property and tie it up for usually no more than $100 for a period of 8-12 months, analyze it myself and if I believe it to have a chance at being buildable I create a permitting plan and market the property to other investors/builders willing to take on the permitting risk.  

Wix is by far my favorite. 

Make sure we're accounting for the appreciation, cost of the sale, cost of the purchase and one of my favorite factors, the risk.

I use all of them:-Brokers-Platforms like LoopNet, Crexi (my favorite), and BiggerPockets Deal Finder-additionally, brokers often have access to off-market opportunitiesWhen dealing with brokers, I've found that you have to build a relationship in order to get a good deal flow.
