I have done a ton of research and spent quite a bit of money getting consultation from lawyers and CPAs over the past few months on how to do this correctly.

We'll need to re-do the walls surrounding the current tub & I was hoping that these all in one's will help us save time & money.

They often hope you'll go easy on the screening process in exchange for some extra money.

Make smart choices by guessing your money flow, asking local pros for advice, and looking closely at the house.

With respect to the equity, If you have 25% equity in the property you may be able to pull out some money depending on what the lenders LTV guidelines are.  

I rather fix the damage, have the neighbors insurance pay for it, and find a new Buyer once the issue is resolved.The important question is: After I say NO to the requested discount, if the Buyer decides not to proceed with the purchase, would the Buyer be entitled to receive their earnest money back or should I?

So I’m honestly not sure about goin in on a property only to lose money.

I have already ran all utilities from my original rehab budget but need about 30k more to finish.Now im 22 and really took the gamble putting most of my money into the original deal so savings isn't really an option.

Now I have an investor who's been paid, and a renovated rental property with a tenant that I haven't really put any of my own money into. 

So I would say spend the extra money to hire the contractor, watch & learn, and start doing smaller tile jobs until you are confident enough to take on a project like this.
