OK so update. I met with the owner, we discussed a price. I got a pre-qualification number on my salary for R1.15mil. He wants R1.2 mil for the house. He wants a VERY fair price, considering the house was valued almost 4 years ago for R1.25mil, and the municipal value on the place is R1.15. The house is worth more.
Anyway, so he said I can buy the house from him on paper for R1.15. The additional R50k he wants I then have to pay back over the course of the next few years. The kicker - I'm getting that R50k "loan" interest free.
So I agreed to those terms, we met up on Saturday and the paperwork is signed. Loans are already applied for and now I'm just waiting for the bond registration. Super fast. The lawyers they are using apparently knows people "on the inside" so they say I can expect registration of the property in my name by middle March already.
