.- >65K in rent collected- having someone to bring in Amazon packages when it is raining outside- generally having someone to watch over the property when out of town oftenI think the headache is worth it.

Which material is best?

I am 70% thru the materials and will likely go back and do a quick review of all materials before siting for the exam.

For example, the iconic Malibu waterfront homes were built directly over the water, many by variance, and assumedly will not be permitted to reconstruct, certainly not with the same materials or attached architecture.

To simplify the existing lease I thought about asking the tenant if they would be ok modifying the addendums to get rid of the resident benefit package and the building protection plan. 

Hiring someone to do the work will likely cost too much (I would charge a small fortune, it's an incredible amount of work) and doing things as cheaply as possible will bite you in the *** later when you start having issues with your own shoddy work and/or materials.

ACM (Asbestos Containing Material) abatement is a tough one because often you won't know (outside pipe insulation & 8x8 tiles which I can spot and point out with no testing).

If you research recent sales you can always provide the appraiser a list of those sales.One of the best ways to insure a higher value is to update the property using materials and fixtures that are popular and common in the area.

Too many flakes and dream merchants (using my material to teach while stealing your wallet and offering to help you look for it!).

Aloha Mark,   we've been doing this for years using various software packages like Propstream and others.
