Also, I see you're a Vegas investor. When I met MMM a the Seattle meetup a few months ago he told me to look into Vegas for rental properties and that he was thinking of doing that himself. A few months later I started hearing that it wasn't such a good market for that anymore. I go to Vegas relatively frequently (via my husband's job) so it appeals to me for that reason. What is your opinion on the market there? A quick internet search for properties shows a lot of short sales and rental prices (based on craigslist search for comps in same areas) that just barely make 1%. I'm wondering what a local thinks.
I am not currently buying in Vegas, as declining rents and increased prices has made the numbers not make sense here for me personally. I have been looking into other markets.
As for the rest, it will really depend on your investing strategy and what you're looking for (things like cash flow versus appreciation, neighborhood quality, risk tolerance, management, age of properties, FINANCING, stability, economic conditions, landlord/tenant laws, property tax rates, quality of tenants, building type, roi, etc. etc. etc.)
Defining your exact investment criteria (niche and notch) will help narrow down and out your research list first and let you target areas and begin networking there (as described earlier).
