You can end up with a nice fresh white on your walls without re tiling.

And find a point outside that will allow the ejected water to flow away from the house.And I was going to suggest doing a fresh sewer line tap at the front of your house, via a path in the lower right hand area of the photo you posted.

I feel the lingering odor will hinder me from finding a tenant to rent this freshly renovated condo.Does anyone have any suggestions on how to eliminate the odor? 

A fresh start might give you clarity on what you all want to do. 

a hydrostatic pressure test to should reveal any leaks in your sewer lines. those generally cost around $200(in DFW at least). and you are correct, a normal water bill would indicate you don't have a fresh water leak...I would call a plumbing company that specializes in slab leaks and have them perform the test. residential service companies will more than likely do it as well but their guy might not be very experienced and for this type of test it is very important that the actual plumber doing the test knows what he is doing...they are basically using a balloon and bicycle pump haha.

I had a similar experience with birds nesting inside my fresh air exchange vent to an HVAC system.   

When you run your comps, are you using comps from when you got the hard money loan, or are you pulling fresh comps before your refinance?

You'll need pots/pans, baking utensils, bottle openers, oven mitts, and all sorts of random stuff.

I've got a few properties with fresh loans I'd like to move under separate LLCs, I'm wondering if I should wait and if time will help my chances of not having the loan called due to transfer of ownership.Appreciate any experience on the topic.

55k of equity is already baked in!
