From experience I'm not convinced on the air purge method.Instead I use a 3/4 HP submersible pump in a 5 gallon bucket & pump fluid (usually the pink 'food grade' RV anti-freeze) through the lines.

Can you plant anything when the ground is going to freeze soon?

And it take us about 18 months start to finish with land planning approval process then construction. you might have winter to contend with we work through the winter we don't freeze we just play in the MUD.

@Derrek WiedemanWhen the bank will discover it they may either freeze your line of credit or worse invoke the due on sale clause and request immediate payment of any outstanding balance.The freezing of a HELOC is unfortunately very easy for the bank to do for any reason, like if you loose your job or change risk profile.

Instead, the previous landlord installed an electric hot water heater so the sale could go through.Has caused the pipes to freeze in the walls by not keeping the door between the common area and the enclosed back porch closed.He heated his apartment using 5-7 electric space heaters. 

Plus, you want to protect your property so the pipes don't freeze and burst which is another set of expensive problems.
