Thanks for comments and information.
The advantages for buying as I see it are:
The adverse effect on my savings: Fair Deal, Jobseekers Allowance means test, current low interest rates.
Current lack of security of tenure. (Have moved twice in last 18 months, not good for my health)
Savings of 450 per month less annual costs. Mgt fees, etc.
Rental costs will increase but my income will decrease.
My commute time is 1hr across the city. Will put that time as a radius from my job.
Hopefully I can find a suitable property in the Wicklow,Kildare or Meath region.
Will update when I make progress.
Again thanks for the external voice.
