Would this be a good wholesale property?

[Mohammad Haidarasl]

I am just trying to identify good wholesale opportunities, as I'm new at this. 

I found a property in San Antonio, Texas

So far, these are the statistics:

Appraised: 72 k 

Improvements: 61,620 k

Land market: 10,380 

The way I understand to check on whether or not this is a good deal (I have not gone out to see the property nor have I spoken with anybody) is the following:

20% Higher than the appraised value; thus: (72k x 0.20) = 14,400 then I add this value to the original number, thus 72 k + 14,400k = $86400 k 

Then I would subtract 30% of this value ; so 86400 - 25920 = $60480

The last step would be to subtract the improvements; thus in this case our improvements cost more than the value I received...so this wouldn't be a good deal where there is any money to be made. 

Is my thinking correct? Help! 

BTW, I'm using BCAD.ORG as the website I'm getting property info from.
