I knew that my market was heating up quickly and selling my house would free up a good chunk of cash for investing.

How do i address the heat & water included in the rent in my calculation?

We've used the Schluter underlayment in the past and never had a problem with grout or tiles cracking, and if you were concerned about the cold, you could always run radiant heat.

There was a wholesaling panel not to long ago at RICH that I think you missed but apparently it got heated... 

We are in the heat of spring market here.

Unfortunately gang ,there are "cocky and arrogant" individuals in any ,practice,trade,endeavor or profession.Plumbers with a disagreeble arrogant and surly nature do not last long where I come from.It is highly competitive here in So Cal.You gotta be a "Superstar".Having said that,,,there is also a Code of Honor amongst tradesmen in any town or city.We all know who the good guys and the bad guys are.The bad guys are "disowned" and get put on the blacklist,,,they do not get referals or reccomdations from reputable contractors.We also watch them very carefully and inform our friends at the supply house,,,,do not give these guys credit,do not recomend them,,,they are trouble.We know "The Good,The Bad and the Ugly".But get this,,,good guys tend to hang together and refer each other.They also tend to join credible contractors associations like the PHCC Plumbing Heating and Cooling Contractors Association.Heres a tip ;if you are fortunate enough to identify and hire a good licensed plumber,he will usually know and be able to recommend a good electrician,HVAC man,carpenter,tile setter,painter,concrete and masonry contractor,locksmith,roofer,landscaper,,,you get the picture,,,,Oh Yeah about that business of "plumbers savings lives".Well,,,That is a true statement,,,,that fact is,,,"Plumbers have saved more lives than Doctors,,,,"An old American Standard slogan was "Plumbers Protect the Health of the Nation",,Well,,,Its kinda corny guys but it's TRUE,,,,Why ?

About two weeks away from putting in my first under floor heat!

Also, (might catch a little bit of heat for this) since stumbling upon Rich Dad Poor Dad, my mentality and future goals have completely changed.

Had a lot of perspective tenants turn away due to house not having natural gas but having water heater and central heat ran from propane .

Everything within the house (appliances, floors, walls, roof, heating, etc) is in decent shape, nothing glaring that needs immediate attention.
