Shingles and everything associated with the roof like flashing, vents, tar paper, nails and ridge cap.

I am talking about a computerized printout report of the actual day every payment was made.If you are picky about the tenants credit and financial history, you should require this as well.You should also require the seller to have the tenant(s) sign 2 forms:1) Form giving you permission to access the tenant's credit history any time in the future.2) Notice of a new property owner and where the lease payments must be sent in the future.3) Tenant acknowledgement of a new person/company having total access to the tenant's credit, financial, and personal history.I feel all of this is just the beginning of the requirements prior to closing.

First it was the roof shingles, then the new vinyl windows and even the gate repair and landscaping.

We also had shingles and or building materials to go with the sale of the property.What was the outcome?

One thing I am doing since this is a long term investment is that all homes must be in A+ condition, vinyl siding, shingle roof, with all appliances and move in ready, I don't want lots of repairs to start off, so I pay a little more for quality and everything is bought with cash.

I buy 1990 and later model, vinyl/shingle 3 bed room homes.

Has a layer of 3 tab and a layer of arch style shingle on top. 

Example: If your scope of work says "Tear off and replace roof" and your appraisals states there is a shingle missing, you must also update your scope of work to show "replace missing shingle referenced in photo XXX". 

Many with terrible roofs that look 30 years old, where you can see bare wood in many spots with missing shingles. 

Who will notice the four extra cars parked in front of the house, the dead grass, the shingles that blew off in last week's storm, or the six unauthorized Pit Bulls in the back yard?
