Since I've heard the economy will be reset at some point, I have a good suggestion: make house prices more realistic and depend on the city.
San Fierro is based on San Francisco; it should be the city with the most expensive and overpriced houses in San Andreas. Make the average Ocean Flats or Juniper Hollow house cost more than 1M.
Then Los Santos, based on Los Angeles, should be next, with high house prices but lower than SF. Make areas outside the main city (Ganton/Willowfield/Idlewood) cost less than areas in the rich part of the city (Rodeo, Marina, Vinewood).
And finally Las Venturas, based on Las Vegas, which is the cheapest of three, should have low and affordable house prices for everyone.
Small towns in Red County / Bone County should cost even less of course.
