Anyone have any insights or dealings with Travis Abbott and “Rentals 2 Retirement”?

Here is a great place to meet other investors like yourselves - https://www.oreio.org/ Not quite sure if once you acquire that property if your intent is to manage it as well for some insight into property management give us a call https://peartreegroup.ca/. 

Based on my calculations and preliminary research, I have found that the Bay Area offers good returns from developing land, although acquiring level land and obtaining permits can be challenging.I have a few questions:1) Is it recommended to purchase a complete house plan from online sources like ePlans or similar websites and then customize the architectural design before submitting it to the municipality?

You are going to privately lend an investor on this deal and you will offer them 85%/100% at 10.99%.

Additionally, I offer my clients my experience as an investor as well as my network in order to help them accomplish their goals.

But, if things go well. so far, i've heard from my brother that the owners of the property we are aiming for, are being difficult and wanted us to make the offer before looking inside the physically looking inside both the units of the duplex. 

Texas has a lot to offer, and it sounds like you’re on the right track!

Would you have insights/experience with this?

@Greg Scott Thank you for your valuable insight!
