If you are going to continue to invest out of state then I would try and figure out your goal then narrow down on markets that match that goal, since inventory can be much different from city to city.

You are correct in that is will vary by location and specific property.Closing costs: Most likely between .5% and 2% I would contact your lender to narrow it down for your situation.Insurance: In my area a duplex might be between $100-$200 a month, so I would get in touch with an insurance agent and see what you might be looking at.Taxes: It could be 1-2%+ of assessed value.

., but the older ones, which are in your price range, while still one floor units, will have steps, narrower hallways etc. 

B and at worst C class areas are where people should invest.

So, narrow your focus to one strategy and become the best you can be at it.Best of luck!

There is only room for one car to park in the back and parking on that narrow street is not going to work.

Like @Katherine Robbins said, you need to narrow things down to a particular city and once you´ve done that, then dig into the best agents & property managers to help you.

Just don't let a bunch of people pull your credit til you've narrowed down your search. 

Then you can narrow your search areas down to the highest rent zip codes for 3 bedroom or 4 bedroom homes on the list.

What's your exit strategy a, b and c?
