Most states do not require you to provide receipts.However, if you think the tenant will push back on the charges, show the evidence and stop the argument before it begins.

Always document the evidence to support your claim. 

Evidence may include:two months consecutive bank statements or electronic transfers of rental payments for existing lease agreements, orcopies of the security deposit and first month's rent check with proof of deposit for newly executed agreements.See Treatment of the Income (or Loss) below for further instructions.

Where’s the evidence?  

To maximize the number of transactions you’re involved in you will need to:Be Top of Mind when they think about moving - which requires consistent reminders.Be seen as an Expert – which requires a consistent message and Evidence of Success storiesGain their Trust – which requires communicating integritySo, start out by listing everyone you know in an Excel spreadsheet.

They also allow improvements (with documented evidence) to the property to be backed off the sales price for basis.If you do not need the money and don't mind the cash flow, consider owner finance and carry it out for years.  

-What kind of evidence / document is need for the back up?

I haven't frequented enough meth labs to know, but I assume that there would have been strong evidence of a meth lab on the property.Depending on your area, the tenants may be able to get a copy of the police report.

If that policy is canceled and the tenant doesn't provide evidence of insurance as stipulated in the contract, the contract has been breached.8. 

The lack of payment can be due to the tenant not paying or paying late.Legally, I don't see that you have any evidence of anything but lack of communication (from what you posted) and/or a late payment by a few weeks.
