Thought about this... Instead of a smarta$$ answer, I shall submit what I really think what I'd do...
First, I would purchase (though not completely pay off) a moderate (read: just right for me) home with a large fenced-in yard with soft gravel and obstacle courses and an area of concrete for different training/interests for my dogs. Also, I'd like a shaded area of grass with a bench, etc for reading for me and a "time-out" from play for my current beasts and any adoptees I take on in the future.
Dogs have given me so much - I want to give back..
Next, I like to make real estate investments; again, I want to use the profit to pay my mortgage and start a small business - a gourmet cafe/cigar bar.
Hopefully, in the midst of all of this, I would have a secured a trusted investment advisor and accountant who would help me invest wisely and manage financially in order to provide educations for my great nephews and nieces as well as a retirement and home on the beach for me and so on.
Slow leak it... I've learn to manage without debt/credit and so on... So, I am hoping I could apply it with a cool head.
