Congrats, you have presented a very clear objective, with well defined parameters and with a definite outcome. You ARE the buyer real professionals love to work with.
Here is what you are going to need to do. You will have to start calling local REALTORs until you identify the one who has the stuff.
Here is what I mean. You are looking for communities that are on the cusp of rapid value escalation.
The anent you want will be keeping track of this data for the benefit of their "A" list buyers. You willl need to PROVE you are an 'A' list buyer.
Here is what the data looks like.
Behind the curtain the actual sold prices in the community, will be in the $180,000 range with the growing surge taking this community well above the trend line (a). When that happens the community is fully recovered and profit opportunists are gone. Everyone will be paying retail.
Find the agent who has similar data and follow their direction. Their first direction will be secure your funding. Then the right strategy can be developed for you. The agent you want maintains their own proprietary database. That is what you will benefit from however, you must be decisive. These agents have six investors who are looking for EXACTLY the same thing. If you are indecisive you will find yourself on the "D" list really, really fast.
