How much does a 8000 square feet house cost per month

Too many variables prevent adequately answering this question. 1. Where is the house located? In San Francisco the house could easily cost $10,000,000 or more. 2. In a less affluent area the same house could be $2,000,000. 3. How much down payment? 4. Cost per square foot? The level of finish - high end or very high end? 8000 square feet at $200 per = $1,600,000 8000 square feet at $350 per = $2,800,000 8000 square feet at $500 per = $4,000,000 5. $2,000,000 at 6.5% financed at 100% (no down payment) for 20 years. Your payment would be approximately $15,000 per month.
