You can check with the zoning office to make sure that they know the current structures on the property.

Now I send him a $2,500 check each month.

You might want to check the FSBO websites as well.

@Jack Martin I'll check it out.

When I checked originally to open the line, they had the best rates to begin with.

@Anthony Wick I did check the regulations and there is enough space for it to be legal.

So, here is the question and I hope I do not lose or confuse anyone.I am currently using my check controlled SDIRA LLC to partner and invest with another persons check controlled SDIRA LLC. in a project/business.With that being said me and that individual would like to start another different and separate project using our other regular LLC's as partners in this separate project. 

When I asked how they were calculating it so I could check or learn, maybe I've been missing out something... they weren't willing to share how they were calculating it, saying it was their own way, etc... 

I think on a duplex you can probably get 75-80% LTV, but I am not a lender so double check this with a lender.

While you can find an answer to almost every question in here, both podcasts are a great educational resource if you haven’t checked them out.
