Congratulations Haley! Remember to enjoy the journey. You will learn a ton of stuff as you travel this one.
As for your questions...
1. What do you think is better strategy: invest in a market with lower price points so that I can purchase more properties given the same investment amount, or stick with market I live in at a higher price point since I am more familiar?
Like many others have said, stick to markets for which you are familiar. Yes, you could go to areas with lower acquisition costs, but will it be worth it in the end? It's a toss-up, but I'd guess no, at least not initially. Until you have a strong PM team and experience with a variety of rental situations.
2. What resources /articles/books would you recommend specifically on how to assess and evaluate different markets/cities?
Some resources that may be valuable to you are an app that helps you quickly evaluate properties that you are considering. I use Property Flip or Hold which is only available for Mac (no mobile). I've had it for years and I think it cost me $20 about 4 years ago. Admittedly, my most used tools are Realtor-only tools, but I'm sure there are tools available to the public - just don't pay thousands of dollars for some "proprietary" tool. Remember, we all have either time or money, but not usually equal amounts of both. Pay for what you don't have time to do or research what you don't have money to pay for.
You should also make sure you have an investor-friendly closing attorney that will handle your title work and closings.
Since the market can change in a heartbeat (and sometimes less than that), I'd recommend current articles over books. With the market pace in Atlanta right now, anything published in December is outdated and may not be relevant. Check out the Atlanta Business Chronicle for market info, trends, and upcoming developments.
3. It is quite possible my quick search on Atlanta market pricing is off... if so, what areas in Atlanta would you recommend that I look at that would meet my criteria above?
No, your pricing is not off, IMO. I, like most investor/agents I presume, are on wholesalers mailing lists. I've seen aggressive pricing on wholesale deals as well as on-market deals. If you have cash available, you may try the county foreclosure auctions. There are a considerably low number of properties offered right now, but all you need is one to get started. To answer part two of your question, there are no areas ITP that are consistently below 100k. Even teardowns can be above 100k.
Best of luck to you, Haley!
