I'd give the prospective tenant a choice, 1. one month longer than projected completion and they must vacate on that date because you will be finding a new tenant 30 days before they leave or 2. two month's extra and if there are delays for any reason you will allow them to remain until the house has a certificate of occupancy. 

I have a commercial real estate agent and engineering firm at the ready for all of this.The biggest wall I've hit is rounding up the remaining capital that will be needed to pull all of this together.

by February 15th (or around that date since Feb had 29 days).Its now March 2nd.And now that my timing is off, I'm confused about what will happen to their lease end/move-out date: I had to give them 30 days notice before the end of the lease and not having done so will cause them to occupy the unit past their original lease end date (March 15th).Additionally, if I understand the wording of my lease correctly, if tenant remains in unit after lease ends and without renewing the lease, the "lease" defaults to a month to month...Exact timeline for everything is clearly confusing to me since I missed the date for sending a lease-termination notice... 

EM once given can be tough to get back if the seller wont sign cancellation docs. your money could be tied up for years.. 

I sell the 12-month lease; I'm an investor as well as a Broker and I have found that planting a few ideas about what opportunities might exist for those who remain over the summer usually overcomes the issue. 

Does it make sense to use the historical purchase price etc, and add the equity into the equation somewhere. or use the remaining mortgage.... i cant seem to wrap my head around it. either waySingle family hime Purchase price 460,000down payment 23,000remaining mortgage 416,000reno budget 100,000Rental income 2,300monthly operating expenses 891.00Mortage payment 1873.00 per monthwhat more information needs to be considered. 

Not likely if the outside walls and "foot print" of the home remain unchanged.   

There’s a risk that our cash could be tied up indefinitely. 

This way, the 1031 remains kosher because each exchanger is only dealing with disregaded SMLLC and not a JVLLC or partnership.

I worry that if I funnel money into the existing LLC that should a legal matter arise they can point to the commingling of monies and tie them together.
