The goal of a HELOC is a quick line of credit to either refinance or sell and pay back the HELOC as soon as possible.PS - I would recommend taking a look into the Columbus Ohio market, there's tons of 1% rule deals still within the 120-180k price point with amazing appreciation potential.

This will help attract more business to the state, keep it coming! 

Also, would this loan help build my personal credit, or would it only report to business credit bureaus under my LLC?

You are still going to get the best rate possible with your significant down payment and with good credit I'm assuming.   

They could even hire you to do the work on the house and instead of paying you they could just give you a credit at closing.

You also get 100 free credits on sign up so great if you just need a smaller list done. 

Assuming you go the HELOC route, another option to reduce your costs assuming you have decent credit is to look at credit card balance transfer promotions.Back in 2003-2004 I had HELOCs on my investment properties and interest rates were increasing.

The interest would be tax deductible due to interest tracing rules. 

Beyond immediate safety concerns, the long-term financial implications, including taxes, are a pressing issue for those impacted by the disaster.

Selling the property within your Solo 401(k) and returning the proceeds to the account simplifies compliance and ensures tax-deferred growth (or tax-free in a Roth Solo 401(k.)).
