1. If your comfort level is being near your STR, then sure...look closer, but as @Mel Adams states, you do NOT need to be close to it (even if it's your first one. Our first one is 4.5 hours away and we have one in CA (and we're in NC). I'm not driving to my STR to fix things or do a cleaning regardless if it's 20 mins away or 20 hours away. Build your system, your team and things work out. We've helped many people who own properties nowhere near their home town.
2. We have purchased in all markets. We've bought a home for $88k just 2 years ago that now appraises at $210k+. We paid full retail & high price for our first coastal property, but the numbers still work.
3. Advice is "Don't wait & take action". There are plenty of properties being sold every day. Others are buying in this market and in any market and do well. You've heard the saying "you don't need a home run on your first deal". I agree...but I believe you can't even get a single if you don't step up to the plate and swing. I WISH I would have taken action much earlier, that's why I'm not slowing down now!
Best of luck!
