Somewhere in the middle is likely your best bet for a 20 year timeline.I have almost 50 units here myself and that's about what my portfolio is cash flowing at this point combined LTV is around 65% as loans have gotten paid down and values have went up.

Quote from @Josh Deschene: Hello All,This is my first post and I will try to summarize as clearly as possible.

We do lending and we ask the question - if you have been doing this for ten years and don't have any money where did it all go? 

As explained in this article, seller financing works best if you understand the needs of the seller.https://www.biggerpockets.com/blog/seller-financingReally dig into this topic and ensure you understand it and are prepared to use it.

All this is to say, I believe it would be money well spent for sure... 

Happy to talk through this in more detail and good luck with the out of state investing!
