But Now, in my area, not only does a plumber have to be the one that touches that, but I am "supposed" to hire a plumber just to demo (i.e. remove a toilet or vanity) the house. 

I suppose the underwriting will come in after I have finalized on a property or a few properties after funnelling them through with initial analysis.

One in on standby in Clemson and ready to move in, was supposed to stay through the weekend but I will probably have to refund them everything or close to it.

I suppose the picture is painted rosier at the beginning..But maybe that's the expectation in the Detroit market.  

I'm currently renting the house month to month to a traveling nurse who's supposed to stay through November.A water mitigation crew came in and tore out some drywall and dried everything out and then a sister company then came out and gave me a quote.

It's supposed to ensure there are no surprises after closing.

I suppose the best risk is no risk, but for as much as everyone immediately jumps to the "omg...alcohol, such a liability!"

What if a horse gets wire cut, or bitten by another horse, what if the veterinarian bill will be $10K what are you supposed to do? 

I dont have much specific advice to help you with this one as it appears you may have just blindly trusted the system you bought into and now find yourself in a pickle.with these types of assets it rarely gets better so careful throwing good money after bad.U may need to just liquidate and and regroup.I dont suppose the company you paid for all this education and system is stepping up for you hear in a financial way ??

I have been offered to invest as LP in multifamily apartment deal.Underwriting is supposedly conservative and based on current cap rate (4.5%) and interest rate (7%) so if interest rates go down (which may as Fed has already started cutting rates), returns can be better than the projected ones as can have more buyers for Class A property in few years with lower mortgage rates.
