Not sure how I would feel if I had gotten divorced and got your letter, but hey, I'm not everybody :)

You can DM me if you want the specifics on my commercial experience but I think I'd be thinking: 25% down, 20 year amortization (you can probably get 25 but I doubt you'll get 30), it's probably going to be a full-recourse loan, odds are the interest rate will only be fixed for 5 years and then there will be a balloon payment and a reset, and they will likely want to review/approve the insurance policy you have for the property.     

I tend to be long-winded about this and try to keep this letter shorter.We have a daughter in her 3rd year at the University of Arkansas and we live in Dallas County so we only see her on school breaks since we are about 61/2 hours away but I am very proud of her.

I write letters to make the first contact.

Do I send the offer on an actual real estate contract (I am in Florida) or is there a shorter letter  of intent that I can send the offer on?

I would take a shot at putting together a nice personal letter and sending it to some multi-family owners.  

If it does, then you can send a letter to the tenant(s) and provide them notice of the new management arrangement.

This would decrease you balloon balance to 280K. 

Consider writing a letter to the homeowner, especially if the owner is a homeowner and not an investor, especially if it is a home owner that has owned for a very long time.

Usually you could not change the rent before the end of their current leases.My advice: promise nothing, give them new address or online tool for payments, official letter (paper) that you are a new landlord and collect their concerns, needs, maintenance request.
