And when I specifically asked if this tax valuation would guarantee me a lot split, they said it would not, and that is a city decision. 

Quote from @NA NA: I'm sorry, but you have to accept responsibility for these decisions.

The DM (decision maker) is the best person to be in touch with then the next in line maybe the person now she is closest with.. 

I would work with/or establish a team that knows that market well so that I could make a good business decision.

Quote from @Jaycee Greene: Much of that decision is based on what you want to get in $ profit or % return.

I'm contemplating this decision because I'm not sure if it would be desirable for tenants to have an extra room instead just a loft area.

By the time 2025 rolls around, you’ll be well-prepared to make informed decisions.

Before making your final decision, I'd suggest running the numbers both ways - calculate your tax liability versus the potential long-term impact of accepting those unfavorable terms you mentioned.

Also, there are more things to consider than max ROI.Most people start by picking a particular type/style of property that they like for some reason (usually a gut decision).

But ultimately, that's a decision you need to make with your attorney.
