New member here - have found many useful tips & strategies on this site, but was never a member prior to today.I have a question about seller financing calculations regarding a deal that I'm currently working on.I'll spare you the full details of the deal, but I've essentially been able to get the seller to open up to a possible seller financing deal that would get me a great cash on cash return of near 20% on a good, solid property on the busiest street in town.Here's where I'm somewhat stuck (and I hope you can follow).

If I want to keep the property in a LLC, in order to have the separation benefit. 

@Quinton Lantier - Looks like you want to do Fix and Flip yourself and not essentially assigning this to an investor.

But Roof has all the essentials (good bookkeeping, property organization, late fees) with a much nicer interface, so unless you just need a ton of other things it works great.

My goal in the structuring of the deal would be to ultimately leave my grandparents with a passive cash producing asset so that they still have the benefit of the income without the hassle of being a landlord. 

You pay for it, you work for it, you have substantial risk involved, the only person who should benefit is you.  

I think a ton of people would benefit from that including you.Good luck and never stop learning.  

The Bigger Pockets buy & hold analysis calculator does not take into account the tax benefit of long term ownership, which is substantial.

I am sure everyone on BP is a saint but someone may steal the deals from right under your nose.I also think you are underestimating the closing costs.Actually one of the benefits to the area is very reasonable lawyer/title/close fees if you have the right attorneys.Cash close on that property I could stay under $1k.

You essentially intend to fix it up and put new tenants into the property, so the existing numbers aren't as relevant.
