@Dave Foster can give details, but a 1031 is for properties held as an investment (not a flip), so a longer holder period helps verify this intent,

The intent of the question was to understand the pros and cons of rolling in fees as GP contributions and whether it would trigger any red flags from the lender or investors perspective.

@Derick Bonsu,  Your current intent and use of the property are key. 

We have a 14-page management contract that we've added our real experiences to over the years, with the intent of protecting both us AND the landlord.

It is a brand new very modern unit (side by side) ill be the first owner and im using the bigger pockets calculator to analyze the deal.

As far as 1031 goes, you cannot qualify for a 1031 on flips unless your "intent" was to hold and you did so for at least 1 year, then you may qualify for a 1031 (but never on your primary residence).The question to flip it or hold it can only be answered by you after doing a side by side comparison of the two transactions and the net result of each with your CPA.

My initial intention was to clean up units and raise rents as tenants move out, but I haven't had much unit turn over. 

Ill attach the link to the rent control guidelines I'm following, but if theres something you know that I don't please let me in on it!
