New build - old PPR

[BarrenMuffet]

Background:

New build, site already purchased, PP received - tenders now in . Agreed cost with a builder €595k turnkey. (Big house, very high spec etc). I know, I know.......but will be our final and dream home.

PPR: Current value €300k, mortgage o\s €200k. Variable interest.
Invesment property: Current value €180k, mortgage o\s €138k. Investment mortgage tracker ECB+1.25%, rental €900 per month. Never been empty in last 10 years.
Cash savings for build: €200k
Shares: €40k (will be available to sell over next three years)
Emergency fund: €30k (Want this completely excluded from decison)

I want to hold PPR if bank will let us short term (2-3 years) and then sell. I know we are not allowed to discuss property prices, but I believe I would selling at the bottom or near bottom of the market. My partner wants to sell PPR and possibly investment property to reduce our risk exposure.

Basically am I mad to try to keep the PPR even short term?

We are both employed full time in private sector, good salaries and bonuses.

One reason for keeping your current PPR is somewhere to live while the new house gets built.
One reason to sell is that the bank might not give a mortgage for the build with the other two existing mortgages.
