A few deals fell through because of varies reasons, but ultimately we had tons of action on the houses and eventually found the perfect buyer.

I understand the contracts, financing ( I was a loan originator), what can and can't be done, I know what keeps you from getting sued, how to set a price, I'm not offended during a walk through if the house isn't perfect and someone makes a disparaging comment (they are thinking out loud to see if it sounds right to them) maybe it's not actually a deal killer.

It's not a hotel, the houses won't be perfect (unless it's new construction or luxury). 

The three properties referenced above: a) one turns into a mid-term allowing me to get higher than normal rents that cover everything; b) one turns into a short term; c) the third I focus on getting the highest dollar with short fall of may $100 per month and planning to raise rents in the next few years to cover that eventually.Problems: I have been a long time airbnb user.

Tenant is paying perfectly....except their late fee. 

Proximity to attractions, restaurants, and transportation can often outweigh a perfect rating.

This idea is not new so he saying you pay off all your property in 7.4 years if all conditions were perfect . 

She said the tenant was basically a perfect tenant for the last 11 years with never a late payment or noise or damage complaint. 

I have a nearly perfect credit score and I'm gambling on that for my first project.

I would check this list out if you want to absolutely make sure you're getting a lender that has that perfect combination of trustworthiness and solid terms!
