I am currently living in Missouri; I have one house rented out and am planning on getting more.

I believe everyone's first property should be a house hack just starting out and happy to explain how to do it.

I'm currently conducting research focused on Section 8 housing and am seeking industry veterans for 10 minute interviews.

You would think the listing agents would look this stuff up prior to putting the house on the market, but sometimes they could have bad or old intel.  

Minutes away from Sanibel Island.Main house is a 3b/2ba renting for $2600Duplex on same lot is 4b/2ba split into two 2b/1ba collecting $1900 in rent EACH.Purchase price of home was $662,000 with closing costs wrapped in.

What do you find as the best data source for house prices? 

In this episode it talks about rental arbitraging many units in apartments and then being awarded government contracts where you house a large amount of government employees  and the government pays you well over market rent.

The only time I know of recently in the US when house prices dropped was about 15 years ago when banks had been lending money to people that should never have been given loans.

Repair foundation, updated siding to front of the house, used medium to high end finishes, beautified the landscaping What was the outcome?
