So, I called the appraiser and explained that I would meet him on site to go over the paperwork.  

Quote from @Collin Hays: I visit fairly often with investors looking at a certain vacation rental property to make an offer on.  

Average rental rates, vacancies, competition, growth, appreciation, etc..Ive heard of scrolling through Zillow and collecting information by looking at properties for sale/rent but was wondering if there is a site where all of this information is easily accessible or any ideas for better ways to go about it.Thanks in advance!

Rare do I hear of recommendations but I do hear people asking.I would think in any big city you think about, a visit to a local NARPEM meeting or 2-3 visits would be a great idea. 

You can visit the property, contractors, etc where as Detroit will either involve longer travel or trusting someone on the ground when you arent physically there.

Things they did bad which I wish I had asked more information about:Never involved in the screening of tenantsThey recommended keys for cash by waiving the rent amount buy only collecting fees which they would get not meThe cost to evict is 750-950 yet other companies told me they will include eviction in the priceThe tenant didnt pay in full last month and I was the one calling out to them and asking questions then a few days later I get an email saying something happened with the tenant and they are investigating.You get passed from person to person every week or so.No one told me when the construction was complete and so the house was ready for a week and the post to zillow and other sites was not done.It took them another week to take pictures and then another week to upload it.I was paying 200 dollar a month electric bills while the house was vacant because they left the AC running in the empty property.

I'm new here to the BiggerPockets site.

I had not heard of the corporate housing by owner site.
