'Serving all Your Real Estate Needs'
There are a lot of resources and most give general data. For specific data you will need to have access to the main systems such as the San Antonio Board of Realtors MLS or have someone such as myself gather the specific information for you and share it.
As an investor I look at the very data you are seeking so I'd be happy to discuss this with you.
Please call me at 210-232-2310 to discuss.

Nothing will replace an experienced agent running you comparables and sending you up to date lists of good investment homes... but you can do a lot of homework on your own as well..
Home investment is not just all about numbers on a computer screen though... I did 1498 investment homes over a 10 year period... and must have looked at literally thousands of homes per month, and all of them were purchased based on gut feelings and the comparables in that specific neighborhood... and the best advice I can give you is... SPEED is the key... when you see one that looks good on paper and in person... you have all the time in the world to send them a solid offer as long as you do it in the first 5 minutes. ;)
