All the advertised rates that you see are for owner occupied and ideal circumstances (credit, condition, value, etc.). 

Women really like dudes who can fix stuff.

For the other expenses that you deduct, like internet or home office I would talk to your CPA about that, the rules and individual circumstances vary so much that I think its hard to give general advice on a forum.When you make the change you should also be sure to notify your property insurance company and update the names on your utility bills.

Under no circumstances should you purchase a property that doesn't qualify for title insurance...

It can be a very good deal for the landlord and tenant in the right area and under the right circumstances.

@Latierra Dewberry this is such a loaded question based on your own set of circumstances.

Is buying all cash the smartest first step to ownership under these circumstances? 

I am facing the same decision but not quite the same family circumstance. 

I am sorry if I come off too strong it's just these are the types of questions where the answer would vary depending on the individual and circumstances. 

You are able to get out of that term if there are certain circumstances...Like a sudden change in job, that requires relocation, or other life circumstances.
