I can share over a list of neighborhoods.

How did you get your list for your direct mail campaign?

I am the listing broker, lender, acquisition GSD'er and team captain ;) and worked with my investor partner to make it happen

Getting your Real Estate license is a great idea for flipping houses you will be able to save 2.5-3% when you buy (if listed on MLS) but definitely when you sell which is a nice added cushion in case unexpected expenses come up especially when starting out!

Ask him if he is a listed "insider" with the builder. 

You might need to improve the attractiveness of your listing. 

If so, sounds great -but the reality is that this means they are only going to list it on their website and maybe Zillow, but not on any MLS so other agents can see it and bring prospects (because agents expect 50% of one month of rent to do this!).

Looking at a current listing in Austin (MLS number 5473496), this is 3503 E 17th St, Unit B4.

That said, I have had some luck responding to code violations by reaching out directly to the city agent that is listed on the report they send to you.

Just a reminder that even if he owes you the entire security deposit, you need to follow your state and local laws regarding notice to him showing itemized deductions from security deposit, any balance left or balance due to you, and proof you sent to last known address, I believe, even if it's your own unit, as he could have put a forwarding notice in with USPS.
