Your land drainage has a lot to do with how well it drains off surface moisture which includes your aerobic system sprinklers as well.  

As long as tenants are paying utilities and the crawl space has no moisture or mold issues there is no reason to change.

This is in a condo complex and I requested HOA to send a gentle reminder to that neighbor for being courteous to others- but unfortunately it hasn't helped.

I'd bring these items up, very gently and kindly ask that you be granted a waiver - you lost a lot of money when they told that you couldn't rent years ago when in fact, maybe you could have?

Here is a part of the letter, I sent to the seller:The home inspection was completed on September 29th (please see attached) and the following issues were pointed out: 1.The wooden floor frame in the middle unit is deteriorating due to either prior water leak in the bathroom or due to moisture infiltration through the walls and foundation.2.There is evidence of significant settlement under the middle unit bathroom and north closet.3.The settlement of the floor and walls has also resulted in settlement of the roof frame above this area, ceiling shows cracks.4.There is an obvious depression on the roof – water is ponding on the roof above the middle unit, which adds excessive weight on the roof and potential for leaks.5.Asbestos containing material has been found.6.The current bedroom heat installations in the north and south units pose a safety hazard from carbon monoxide, fire and oxygen depletion.7.An electrician performing upgrades did not use ‘arc fault breakers’ in the north and south unit breaker panels, which is required by the national electrical code.8.Upgrades to the electrical system, promised by a real estate agent, have not been completed yet.

The seller has offered to finance at 7.5%I contacted to seller to ask questions and get a feel for his need to sell but he is only dealing with me via Email, and I still only know the cross streets.I asked him in my last email about the Lot size, the Address, if the are any back taxes, if he is the owner or someone selling for the owner.....Questions:If I am able to talk with this gentle man on the phone, what do I ask him?

Gently serve copies of said time stamped legal documents to your "tenant" and respectfully ask for the arrears.

Tenants will not usually be as gentle as an owner.

@Jonathan Meyers one of the strategies of using a private lender for long term holds is where you buy gently loved (beat up) homes and renovate them.

This is where if you are gonna be a salesman,you need to use your powers of persuasion.Find their pressure points and emphasize you are there to alleviate those pressures.Take control of the negotiations by gently reminding them that you want to buy but can move on to the next deal at anytime.You have to make them worry that if they don't cooperate and comply with your contingencies,you will walk on them.Why are they selling?
