Upon move out, I print two copies and we tour the place again, comparing the previous notes to present conditions.  

Screening includes credit w/score, criminal and evictions checks for $19.95.Pros: Price which is better than most that I have found, The applicant pays online, good customer support.Cons: They don't offer decision advice, The reports are only saved for 30 days then deleted (Be sure to print or save the reports on your local machine) Overall this is the best/economical solution I have found. 

Also do you think its a good idea to print a map of a market im going to target and label the good and bad neighborhoods?

However, you could take the classes online, take the exam and be done as quickly as you can get them both done (along with the application, finger prints, etc...).  

When I increase rent a couple times I printed rentometer and use for backup with my rent increase letter addressed to tenant.Frank

Every time I think I'm going to slip one by uncle sam there's some fine print lol...Any other recommendations to reduce my taxable income when purchasing a new property?

I wouldn't lend to Uncle Sam either as He is practically defaulting by printing money indefinitely.I'd buy real assets so that I can pay my clients a reasonable rate to match at least the inflation.

This would involve a separate lawsuit, judgment, and collection (i.e. a mess) and it might not work.Depending on the existence or availability of any personal assets, personal guarantees are often not worth the paper they’re printed on.

This could go on for days.To add to this or to give an example, I have advertised in national print media.

Could I just print that off and show them?
