I got them to prepare the necessary OAs with my objectives in mind and file any required documents.

While a software might not be necessary at this stage with your rentals, you should probably at least upload all your files (leases, invoices, etc.) to Google Drive at a minimum.

Typically, if they do not file such claims within 1 year, then the transaction is final and the title insurance company will issue a policy. 

Google "IRS tax rates" for your filing status. 

I know tons of investors who have received additional discounts in rate and closing costs for having multiple files closed with the same investor at once.Happy to connect and strategize more creative solutions if needed.

In phase 2 of my growth as a REI, I would have the contractor do the shopping and used Home Depot’s “text to confirm” system where you can see all the items the contractor is purchasing (with pictures, quantities, and pricing), and then you approve the purchase (or deny it) with the credit card on file.

She will not waste money and time to file a Small Claims Suit over a $200 charge when she knows you have evidence to back up your charges.Cut off communication immediately.

Their E&O insurance should cover this.You may need to file something with the local or state Board of Realtors and attorney general.

If you do not, and she stays but fails to pay rent, you have to proceed with giving proper notice to pay, failure of which entitles you to file an eviction.

All you can do is give a polite warning to everyone.We've told many a tenant that this is all we can do unless they want to file a police report.
