Tenant should pay for all repairs during the tenancy (agreement to this clause may indicate if it drains and plumbing were kept in good repair.) 

(Having a back up also recommended).Have a list of those you can call for appliance, ac, electrical and plumbing issues.

Chances are they would require access to the crawl themselves to see the plumbing down there.  

Some of my key takeaways were that it is important to define exactly what you're looking for (Crystal Clear Criteria - CCC) and that, using the stack method, financial freedom through small multifamily investing is tangible and achievable for everyday folks like you and I!

My husband and I ended up doing everything other than electrical, plumbing, and HVAC.

However I may just send the wholesaler this end buyer in hopes they will provide me a finder's fee.If not, no big deal and I move on knowing this is their method and we won't work out.

That method is cumbersome, time-consuming and bogggles my mind.

I have similar problems with our plumbing and construction customers where customers negotiate, agree to a deal and then try to change the deal so they for something selfish that benefits them and with no concern or regards for your welfare. 

This perfectly highlights one of the top 3 FILURE methods of thinking; the "oh no, I better be careful to have to to owe/pay too much in tax's" lie. 

I am also an residential electrician with many contacts including a couple friends who are general contractors, a friend who is in HVAC, and close neighbor who owns a plumbing business.
