I'm looking to get started investing in the DFW area.

I've been a BP fan for a while, started listening to Brandon Turner and loved the podcast and the concept.

You should not start the conversation trying to secure a seller note or haggle for a lower purchase price.

Does seasoning start when the property is bought? 

Yes. build to rent in urban core adjacent neighborhoods. traditionally in our market in Columbus Ohio existing inventory was good 2014-2020. as prices rose, the cost to build started to match existing inventory prices because of supply shortage, especially for 2-4 multiunit dwellings. around that time we started to look at new construction and land. we found that land is a 12 month or more supply in our market which makes it a buyers market and you can design any structure you want in new construction. if you like a layout or floorplan all you have to do is design it. after that we looked at the right unit mix and Floorplans and layouts. we started looking at high rent per square foot layouts that were better than single family.

There are easier strategies to start your new venture.

You also may need to start with more capital so you are prepared for unexpected situations.

Builder's Risk and General Liability should be a great starting point.

Can some please help me with a game plan of where to start?

I'd start shopping around for terms and building relationships sooner than later.
