. - I am considering selling a few if not all (just 4) of my properties here in TX (I would hope to walk away with about $150k+). - I will be in school full time for 3 years along with clinicals in and around Nashville. 

(The idea being the insurance company doesn’t want you to walk off with $30k and leave the roof not repaired, so they put controls in place to prevent that). 

When I was on the firing line of course we did not have internet like today and Investors were generally local so they would walk into the office . 

Quote from @Yousuf Kaleem: Walk-through inspection.

If you walked up to Michael Jordan and said, "I want to learn sports" he would walk away.

Can I ask for reduction in price or walk away? 

It amazes me nowadays how people will throw money into a market and not spend any time in it(pre purchase) then wonder why it didn't work out.we literally purchased our second stilt house by walking up our stairway and the owner (of our now second str there) was walking up there stairs and we struck up a conversation and purchased it off market.My advice, allocate some of your investment funds to knock on doors and hang in the area you buying- its priceless.

Even the people you think would never lie or walk away from their responsibilities still do from time to time.

In FL that means a pool (unless you are a quick walk to beach), barbecue, nice outdoor area, etc. 

We have bought 4 foreclosures - 3 went great - the other one literally wreaked of cat urine so strong we had to wear respirators to walk into the house.
