Hello and welcome to BP @Ralph Newton! Subject to and BFD are a couple of advanced strategies and they should put fear into you as someone who's never done them. Lease options can be done a few ways and many people use the term interchangeably with lease purchase or rent to own and they are all technically different. You have to do a good bit of homework on this stuff or work with someone with experience to help you fill in the blanks or connect the dots for the parts you don't understand. I'm right up the road from you here in Lafayette and I keep a pretty busy schedule, but I'll be glad to help you when I can.
Some of the best information you will find here is in the podcasts. The hosts do a good job of making the podcasts educational by having guests pause to explain any acronyms or terms they use during the interviews. You might search for podcast and a term you are interested in to learn about each topic.
BFD is a LA unique strategy (term) that is most similar to land contracts in other states. There is a BFD service company in Metairie that has a website that is pretty informative with a few short videos. You can find them if you google LA bond for deed, they will be one of the top results. [I am a customer, but I have no affiliation with the company. :-) ]
