Heard a funny story once where some first-time buyer was at the tail end of a several month FHA purchase and had a surprise divorce... supposedly the realtor ended up "purchasing" his swing-set for $3,500 to get him over the bar for required funds, and had to supply the bank with a notarized letter of purchase so they wouldn't write the deposit off as an un-seasoned gift. 

One of the costs we hadn’t considered was the cost for notarizing all the documents- it came in at just over $300, which isn’t a ton- but more than I’d like to spend each time, especially as we scale.

I would offer a notarized affidavit & see if that works.  

I will send him registered mail with a notarized letter asking when are they going to show up again.

As you'll read on it, your notarized signature also confirms that this loan has been reconveyed (i.e. paid off).

Be prepared to get notarized statements from the contractors that were there, or have your attorney subpoena them to appear in court to testify about the tenant's threatening behavior. 

And you are allowed to ask for a notarized letter from a doctor to state what that particular task is and that it's necessary for the person.So, if you're saying that they're stating that they'll get the dog registered.....that means that this dog is a pet now....and not a service dog.....there is no such thing as a registry for service dogs.

Getting documents notarized if you don't have an attorney will require that you visit an embassy.

I have been studying for a while now and I feel I'm ready to start making connections before I get stuck on whether I should pull the trigger or not. Are

All of our guesses - and that's all they really are, educated or not - are based on our own experiences, values, financial position, abilities, etc.
