I would decide which route is best for you.

I opted to go the HELOC route instead.

So if I understand this correctly, by qualifying to extend the 5 year rule to 10 yrs, $250k if single or $500k if married of proceeds from this sale would be exempt from capital gains? 

Just keep in mind that using that emergency fund to buy your next property and having tapped a HELOC already may leave you in a bad spot if you run into a similar problem again.Also, I’m not 100% sure, but I have heard that personal loans don’t your credit more so than other types of debt so be sure you look into that if you go the personal loans route and then planned to finance your next purchase soon after.

I do have it correct outside, but when I run reports through Stessa, they aren't accurate.  

If you go this route, be aware that you’ll lose payroll deductions—so you’ll have to track contributions on your own (see IRS Publication 969 for HSA rules).2.If You Own a BusinessIf you’re running an LLC or S-corp, you might be able to fund an HSA through that payroll.

If it does go to probate, hopefully your brothers and you can amicably go the informal route vs formal (I've worked with families in both when buying properties out of probate and informal is FAR easier).Since there's no debt on the house, maybe you could sell with financing or maybe you could even buy out your brothers with financing -- that way you maintain ownership and just pay them a monthly amount.

Correct.

I just re-read and realized you're talking about getting loans for lien position 2, is that correct?

An easier route would be to convince him to go in on the short term rental together in a partnership.
