And how long did it take to sell.

I never understood why people would have a flip, boost the value by tens of thousands of dollars, then sell it as opposed to keeping the equity and putting a tenant in there. 

While there were many "Na-sayers", we sold the property above list price and well above what others thought it might sell for.

Quote from @Meliisa Lee: I recommend splitting the properties or selling them off and splitting the proceeds.

If I sell this house today, I can get $460K but I still have mortagage to be pay off which is about $350K.

If so, am I selling/transferring the title or am I just adding the entity to the title?

Hi Shayan, You will be able to close on properties quickly and have access to rehab funds immediately if you are able to qualify for a HELOC that can cover both the purchase and rehab.You should be careful though as if you cannot sell the property or you run out of rehab funding, you may end up being over leveraged.

The seller can often sell a property that can not otherwise be sold, financed, or sold for enough to pay off existing mortgage or obtain a higher price by selling Sub To, or Sub To wrap/owner finance.  

If it is your primary residence as indicated, just sell it and skip the 1031I Persue all 3 payment options concurrently and see which pans out as your best deal.

But, we now live across the country and managing from this far just doesn't make sense for us anymore so we are ready to sell.
