Maybe just say you are taking it off the market until the heating issue can be resolved, and offer to let them apply now or later when it is ready to rent.  

I have  onsite managers that take some of the heat off me with the multi family but all the tough decisions filter up. 

We converted it to a rental property the next year after replacing the roof, converting the oil heat system to gas, and updating the electric system to the tune of $38,500 altogether.  

@Aaron Marshall In a 3 unit multifamily you'll have one roof, one common area, often one hot water heater/heating system reduced costs from visiting each unit more often.

Additional NON REFUNDABLE $400 pet entrance fee and additional monthly rent premium of $40.Smoking: All our units are nonsmoking and policies are strictly enforcedLease term is 1 month, auto-renewing, and monthly lease includes heat & hot water unless otherwise stated.2.

If you spend your savings on a property what happens if the heating system goes, or you need a roof etc.

We pay $2,200 with permit pulled on an 3.5 ton AC unit with coil.  

I find it difficult to figure out how you did all of that for only 30k but you did save a lot on sweat equity. my experience is, even if you do the work yourself, you still need help.if you pulled a permit, which I'm sure you did, I'm surprised the village let you do all of the plumbing yourself. that's definitely needed by a licensed guy and registered by the health dept (even though plumbing isn't all that difficult to DIY).great to live in a flip; just would take a while before it's functional to live in but definitely attainable with heat and hitting the local health club to take a shower. :)maybe it took him 8 months from beginning to closing. if it was an 8 month rehab, he definitely spent more than $30k in labor & materials.

The one question I have is about the utilities and heat. 

@Jeff Fruhwirth   I am guessing no heat in Cheyenne in December is a major issue
