My condition was that they rent the house for 1% of the costs and sign a 3 year lease.

A good tax accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant who specializes in business taxation, financial planning and tax planning.I would also recommend looking for a accountant willing to work with you throughout the year.

The one you select really depends on your needs and bookkeepers preference.  

Put it in writing and have both of you sign it.

What are you going to try to "upsell" me once I sign up?

It's difficult to see how a tenant will be after screened and signing a lease.

And, they all sign the lease. 

They have a good selection of quality rugs for reasonable prices.

This is being pushed on out of state investors who don't have a clue what they are signing up for.

If someone has been given POA maybe they could sign it.
