I've been reading a lot of books and have learned a lot from BP podcast and other tools.

Depending on a state's charging order laws, they could still win a lawsuit and essentially never see payment from the asset.  

I am interested in using the Brrrr strategy to grow my buy and hold portfolio and need help.I have spent quite a bit of time reading the forums (and many other sites/tools) to gain insight into southside suburbs and neighborhoods, but the process is just too slow.

Also, your book is an excellent tool for beginners like myself.

If you work with a quality firm and not just a marketing company/document provider, then you will also have access to quality support for the tool as you invest, and can consult with your provider to ensure your strategy is within IRS guidelines.If you are self-employed, there is a similar program with checkbook control called a Solo 401(k) that can have advantages as a more powerful retirement plan than an IRA.

Should I just send an email essentially saying "Hey I'm interested in buying your house through seller financing, I can offer a good down payment and excellent interest rate.....?"

Go under Tools and check out the rental property calculator and start entering the numbers.

Sure, there are headaches, but you are essentially having a tenant pay for your asset while you're also collecting a profit from them if you buy right and it cash flows. 

Instead of prospective tenants you have potential buyers or sellers.The tools are there if you can just think of it as property management but you are using it for land.You can keep listing data, pictures, contracts, deeds, parcel maps, advertising propaganda etc in the property file/page.

Run the numbers on the BP calculator (under the Tools tab).
