@Dan CrenshawIf the boiler has an anti-freeze setting, I would have it enabled and configured, if not, you can install a control to override the internal thermostat which will keep the house at a minimum temperature and will run the boiler every X minutes/hours as a freeze prevention.We have it written in the lease that tenants must maintain a minimum heat of 10C in the unit even when they are away, and that they will be responsible for any costs arising from frozen plumbing within the conditioned space of the unit.Where this is not the first time your tenants have done this I would pass though the service costs to them.  

AZ is 1 of 7 states that has an anti-defeciency clause to protect some homeowner's during foreclosure/short sale.

(I know that's a stretch for you anti-guru types who are the majority on BP... but you have no idea what you're missing/and what it is costing you by NOT learning from legends like Peter Fortunato and Jack Miller) Peter has no home study courses or books to buy.Creative financing cannot be cookie cutter.

The ONLY product that I found that will work is called Anti Icky Poo.

SAMPLE LETTERS**IF YOU HAVE A REAL ESTATE LICENSE*Dear Senator [name];My name is Vena Jones-Cox and I am a life-long resident of Cincinnati.I am writing you to encourage you to vote NO on HR 1728, the "Mortgage Reform and Anti-Predatory Lending Act".While many of the provisions of the act are positive steps toward mortgage reform, the inclusion of private owners in the act (see section 101(3)(e)) will enormously reduce the housing choice of Ohioans and the ability of home owners to sell properties in this already-slow market.As a real estate broker, I have seen several dozen cases in the past year of home sellers and buyers coming to an agreement for an installment sale on a property that the owner desperately needed to sell (often to avoid foreclosure) and the buyer desperately wanted to buy, but could not raise the downpayment needed for conventional financing.In all cases, these sales turned out to be win-win deals for the buyer and seller; the seller was able to get rid of an unwanted property to a buyer who loved it, and the buyer was able to get his new home at an affordable payment and interest rates with none of the usual costs (points, application fees etc) inherent in more conventional mortgage transactions.In Ohio, these transactions are already regulated by state law: a low maximum interest rate is already in place, and both the buyer and seller are protected by other regulations at the state level.In defense of private property rights, owners should be exempted from the burdensome and unnecessary rules that this law foists upon them.

But laws and regulations have changed with anti-stalking efforts which have made "heir hunting" all that more difficult. 

That is:The vast majority of people who buy guru courses never make their money back.I am NOT anti guru.

Plus Getting bedazzled by an anti tank grenade makes everything else seem like a walk in the park IMO anyways.My Milestones to date:*Come up with a catchy Business Name & Logo*Got my business Incorporated through Nevada*Created the business Website [REMOVED]*Find a Hard Money Lender for Transactional Funding*Find a Real Estate Investor Friendly Title Attorney*Implemented Marketing campaigns within the last month*I now have 50 Property Locators*Craigslist FSBO Seller ad campaigns*Bandit signs*Direct Mail*Door knocking and cold call campaigns*Business Cards and Credibility packages like Brochures and magnets.

That, in itself, seems to be anti-conservation - you can't simply use as "little" hot water as you please - since the tankless heater may not sense it.Rinnai seems to be a good brand (it's the only brand my commercial HVAC friend installs).Bear in mind, it is sometimes easier to relocate the (tankless) water heater so that it is sitting against an exterior wall (so you can easily vent it) and re-run the plumbing to it, than trying to get the necessary large vents (which typically cannot be shared) run to an exterior wall.

It is possible they have a anti scam policy.
