Hi Salsa!
How exciting! See if you can grab a copy of the recent results - in Sun/Mon papers and keep a bit of a log with some notes bout area/house etc to give you a feel for the prices. Depending on the agent's they all have different ranges/expectations. If you know what area you are after and are keen to move quickly you can purchase area reports - but it is hard to differentiate between the properties if you don't have access to floorplans etc...
Good Luck!
