My other concern is the timing in putting in an offer on a house while trying to line up a renter, but that is probably among the least of my problems. 

You need to be concerned with getting your first deal done, and doing a deal that cash flows.

Sometimes I have to leave a bit in the deal when I refinance if the deal isn't perfect.Short answer is let your cash flow decide how much you need to finance to get the cash flow desired.

I am unsure if this is allowed but they can't expect me to leave it vacant so it's worth a try.  4. 

I expect my rental income to cover mortgage payments of course, but I can also cover things as needed by pulling out or borrowing against my stock investments - so losing my active income source isn't a huge concern for me.

I have a few close friends interested in becoming RE Agents but are not yet ready to leave their day-jobs to do so.

Class D,F should be all electric to minimize fire risks (leaving stove on etc) a Class A properly might expect a gas stove.

Is it bad that I want to leave it as a "As is" ?

Should I be concerned with that ?

If so SHE is in breach of the lease.The other item here is she seems ready and willing to file a lawsuit over your breach but does not seem concerned about her own.
