In this way cap can be improved.I am seeing however lots of sellers and listing brokers where the property for that value has already been extracted.

Would need to know what your purchase price is and the area it is located to give any meaningful advice

Hello @Bhanik Shah,  With the small amount of information you are providing it is difficult to comment in any meaningful detail.  

The good ones share meaningful knowledge and sometimes how they operate.

However we've had terrific success in the area as ROI is more meaningful to us than income.

Mind you this is partly why investors (including Mexicans) prefer to invest with me rather than investing on their home so these risks represent an opportunity for me since I personally know the developers we are dealing with.I am looking forward for more meaningful exchanges with yourself, whereby both of us contribute to deepen the knowledge of the members of the BiggerPockets community. :)

My question is once you hit retirement age, how is the property extracted from the IRA ?

You can't expect any meaningful feedback with so little information on your situation provided. 

You can always get a loan against it to extract the capital later or use it as collateral against a bigger purchase.

Extracting money via a refinance from either appreciation or value adds do not get taxed until the property is sold.
