@thejeepdriver - check your math: $30,000 / $1200 is 25 MONTHS not 25 YEARS.
Further, whether to repair or not really should not affect your decision of when to sell: if the market is efficient, the market should discount the price it would offer for your property by the same $30,000 if you fail to improve it. So the net cash to you would be the same either way.
