GTA SA: Cannot buy properties in San Fierro

[Poisson]

Hey, all. I would like to ask for help. The most recent mission I've done is Jizzy, but I still cannot buy any properties in San Fierro. All of them are marked as red.

 

I've read something before in this thread years ago of the same problem. I did download and placed "openfix.cs" in the cleo folder but to no avail. I just would like to be able to buy properties so I can store special vehicles. 

 

Any help would be appreciated.

 

Note: I have already bought some clothes in Didier Sachs in Los Santos, which for some reason was unlocked even if I haven't unlocked Las Venturas yet, but maybe this info could help describe my situation.

 

Additional note: I also installed mods (but only SilentPatch, SkyGFX, and SA PS2 menu)

The problem has finally been fixed! But before I start, I would like to thank @ArmanCan for having provided mense help as to my issue by guiding me throughout the process.

From reading relevant threads and discussions in the internet, I have found that this info on this particular issue is pretty scarce, and that in finally laying this problem to rest, I hope to also help others encountering the same issue. The process is as follows:

1. Install CLEO first (mandatory)

2. After installation, copy and replace the files to the root folder of GTA San Andreas. There should be a folder named CLEO
3. After moving the files, next is to insall openfix.cs
4. Next, just copy openfix.cs into the CLEO folder
5. Boot up the game and load to the affected save
6. After loading the save file, wait around 4-5 seconds and type OPENFIX as if you are typing an in-game cheat such as HESOYAM
7. Afterwards, there should be a "Relaunching OPENUP script" in the screen

8. If successful, houses should now be purchaseable

Hope this helps anyone encountering the same problem. Once again, thanks to @ArmanCan!
EDIT: Also props to @OrionSR who created the openfix.cs in the first place! Your efforts to the community have not gone unnoticed.
