Estimates I have gotten from a few different contractors vary from $150K to $200K.With my current day time job I have flexibility where once I fix this place, I could rent out my current primary home and move into this new house.

I schedule all showings for the same day/time. 

I would add, as being somebody who has been doing 1031 since 1986, its not as easy as it looks, there are hoops to jump through including, but not limited to the required 45 & 180 day time frames, and most of all, if you want to see how fast 45 days can fly by, start a 1031.  

My understanding is that you do need to provide heat and hot water though so I'd try to get it fixed or replaced sooner than 8 days from now if possible.I don't know that you'd have to pay emergency overnight rates, but if it were me I'd try to get someone out for a daytime call within 3 days.

I just recently quit my night shift job (12 hour shift, 60 hr weeks...brutal) and just started a day time job (8 hr shift, 40 hr weeks...

The closing date on that offer is getting within the 30 day time to close window.

What's kind of confusing is that both the reverse part of an exchange and the regular 1031 exchange have 180 day time limits.  

The 60 day time frame is generally accurate. 

The 45 day and 180 day time limits begin with first sale.

If you're heavily in debt these won’t work but since I have none I’m putting all proceeds from my rental and my daytime job towards it and using it as a checking account.
