I assume no roof or flooring changes and it was already taped/floated.

And maybe negotiate a floating or extended closing date of 30-60 days to accommodate any last-minute construction hiccups.Buying new construction to complegte a 1031 should be a relatively simple process. 

There's markets where you can keep the float of capital to 30k. 

Children's pool float toys?

I have so many things floating around my head ...

I got there name off of a list that floats around here on BP.

I use it almost exclusively in my rentals.SuperFast® RidgePlex Lite Mist 6.93" x 36.81" Floating Vinyl Plank (19.48 sq.ft/pkg) from Menards 38.75 a box.A tad over 2 bucks a sq. foot click lock.

After refinancing, you can repeat the process.I would use caution when considering a HELOC as a down payment as this is debt, and floating rate debt at that. 

Then they will ask you to float the utilities for a month.

This is a floating goal but it is a place to start.
