You're going to have a tough time finding a lender, you need to increase your pay or find a new job/partner with someone.

As for "investor friendly", I learn this saying from a customer of mine many years ago, "Cheap is not quality and Quality is not cheap".I believe in building long term relationships where both parties can make money.

We refinanced our house to increase cash flow, and that will close on July 2nd. 

You would just want to make sure when the lease is renewed that you increase the rent to at least cover their part of the water bill.

You will not increase cash flow by paying down a mortgage.

Once you have a full year with no transactions for the ebay business you can start making the ebay related chart of account categories inactive to hide them which will clean up the chart of accounts.So short answer is I believe it's possible to do everything under your existing LLC, however It increases your liability and is not going to be a very clean transition on your books. 

We have our own website and also use booking from HomeAway, VRBO,Trip Adviser and Flip KeyOur high season Guest are all repeat customers and word of mouth so they come through our website.One of our high season guest that we inherited, this was his 11th year on property.

There are different thoughts on this, but some like to say just managing so they can blame th owner for rent increases, late fees, etc.
