Happy to connect and talk about options.

It may not be worth using an LLC on your first one.As for the calculations, just put the numbers in a spreadsheet and figure out which option costs you more.

If yu claim one it doesn't void the option to claim the other one.Provided you meet the IRS requirements for both, as a tax strategy, you could complete exclude a portion of capital gains under Section 121 and then defer the remaining capital gains under Section 1031 (@Dave Foster is a great resource for 1031 exchange). ..

Another option could be exporting your data to a spreadsheet for manual adjustments.

Have 3 loans to refinance in the next few years and DSCR's are added to the option list.

I'd like to move forward with option "b".

I'm not sure if any also lend in Canada, but you might want to expand your search to include "non-recourse" just in case it leads to some more options for you.

Your post about summarizes what I figured my best options are. 

HI, Is opening a LOC on my primary a good option to fund flips or is there a better solution to get the funding?

Narrowing down the options will probably come down to comps and city/neighborhood specifics; things like permits.Any good suggestions for finding out how long permits are taking in certain areas?
