depends on the full value of the house, as homebuy shares will vary depending on this. If the house value is between around 75-90k you'r elooking at needing between 17-20k annual salary. every time you step the vaule of the house up 15k look at stepping your salary up by at least 2k. this is based on having enough left over to live comfortably every month and I'm basing it on homebuys i've seen in my local area (Medway, Kent) so it may differ. Just out of interest, if you're looking at homebuy and you have a sizeable salary to go for it try applying for a mortgage, remember with homebuy you will buuy part of it and rent the rest, it can be very hard to sell on or save up to move out with this
