If the ex-tenant signs a binding agreement and defaults, can I use that agreement to hire a collection agency? 

Some of those sites give examples of what they get so if the letter provided to you looks like that you can investigate further.There is only national registration for service dogs and you can confirm the animal's registration and owner's name with that agency.

If the seller would agree to sell us the property prior to it being listed, at an agreed upon price using a closing/title agency to complete the transaction, we will pay the realtor a finders fee.2.

To date, I haven't personally signed anything other than the original offer and a W9 for buyer agency (self representation as GA broker).

I’m a single family investor located in Dallas, I’m looking to overhaul our in-house marketing and hire a marketing agency to help us with digital lead generation whether they be SEO, PPC, or other techniques.

Dont sign an agency agreement until you know you want to work with them

Another option is to find collection agency, but they will take at least 30% of whatever they collect.

I have build, scaled, and successfully exited two marketing agencies and I am looking to build my third.

The key is checking with the entity that regulates motor vehicles, tag agencies, etc. 

I have a marketing agency and I'm looking for feedback on what's needed in the marketing space.
