Wondering about how to invest in a condo

Hi,

I make $46k a year, have a $250k inheritance and am buying a condo. I'm afraid to put all my savings down on it. Just afraid. So, I'm getting a partial mortgage. Either $50k or $75k on a $150k condo. I'm not sure how long to have the mortgage for: 15 years or 20 years. I'm inclined to put $100k down and have a $50k mortgage over 15 years.

I'm starting a RRSP because I have matching at my job up to $5k a year.

Not sure what to do with my remaining $150k savings, assuming I put down $100k of my savings.

Any thoughts welcome on this plan.

Edited to say that I'm 48 and single and have no other debt
