How Prioritize Improvements to my Commercial Building? [PHOTOS ATTACHED]

[James W.]

How should I prioritize the work for this commercial building to get more for rent? Here is a list of things that need to be done:
1) stucco and faux stone sidings building to make it look new (not sure about cost?
2) painting ($8000)
3) new roof ($10000)
4) termite control ($4000)
5) new larger modern sign ($7000)
6) HVAC for all suites ($72000)

The back of the building is stucco but the front is wood panel sidings. It has a old brown cabin look which I hate. Do you think it is worth it to stucco it to make it look more modern or should I simply just paint it.

The suites are renting at $1.35/sq ft which is a bit below market rate but that is because there is no A/C in the building since it was built in 1975 and is next to the beach. I got quotes which will be about $6000 per suite (12 suites total).

I got a good deal on this property because it has deferred maintenance. Inspection report says it need a new roof ($10,000) and termite control ($4000) and the HVAC $6000 per suite ($72000 total), So I am looking at almost $100,000 in repairs. Should I do all this first before trying to renovate the building?

My main goal is to get more rent per suite. 10 out of 12 suites are rented out right now. I get about 5500/month in rent right now after all expenses cost and $3500 goes towards the mortgage.
