I love this life!

You should check out “set for life” by @scott trench.Really good book for anyone starting!

These are all questions that I need to answer and account for before I start trying to predict what is going to happen to the market.Lastly, the individuals giving you advice probably have their entire life savings tied up in the stock market.

Instantly, I was threatened by him that I cannot demand the money (as per his lawyer).

You can make sure assumptions based on the condition of the neighborhood and outside condition but there is always a wild card involved. 

Pay someone a few bucks (found thru fivr, task rabbit, or craigslist) to walk thru and use their smart phone to upload a video to you on the condition of the facilities once a week or so. 

CHANGE OF TERMS: The terms and conditions of this agreement are subject to future change by Landlordwith 60-day written notice setting forth such change and delivered to Tenant.

The best and most accurate way is to have a realtor pull comps for you.The next best way is to look up recent sales on Realtor.com, Redfin, Zillow, etc.Make sure you look for properties that are similar in size, condition, location ,etc.You want the properties you're using as comps to be as similar to your property as possible.The best comps to use will be the CLOSED sales within the past 12 months.

In many areas of my life none of those things are possible lol, but this one is.
