Derelict House - Advice

adriaaaan

Hi to you all I am a really long time lurker, but I am looking now for some advice from you seasoned property veterans. I am looking for an investment property in Dublin that requires renovation. I have capital and I can tackle renovations myself, assume I dont need to be talked out of the decision to doer-upper. I spotted a derelict house (two storey with walls only) on large grounds in a decent part of Kildare. (Rather not say where). I found name and address of current owner from landdirect.ie folio. I found the owners current place of work online. (Don't judge me). Based on google streetview theres been no construction or movement in the property for ~ 5 years. Property changed hands around the same time.
I am looking for advice on next steps and I am willing to keep this thread going as advice for others who have asked about derelict sites in this forum to see how it plays it.
Should I:
a) Write letter to address on folio with expression of interest and ask for a meeting?
b) Door knock to address on folio ask for a meeting?
c) Leave letter at derelict site? / Ask around to different houses in the area about it?
d) Door knock at place of business?
e) Online search to attempt to find phone number/email, followed by call with expression of interest?
f) Get solicitor involved
g) Other???

Any advice greatly received
