What is the appreciation potential?

There are a few in my area that I keep an eye on to see how successful they might be and I’m always looking for properties with potential to be something grand.

With the current mortgage rate constraints affecting how many buyers are willing to enter the market we are seeing a lot of borrowers have success with the BRRRR strategy with plans to sell in the next 3-5 years when interest rates go down.Researching potential LTR and STR rental amounts and seeing if holding for a few years is a viable option is a good analysis to do well. 

They mentioned how Dom helped them narrow down neighborhoods for a multi-family purchase and even flagged potential zoning issues before they made an offer.

City has so much potential.

Are there any potential risks or downsides I should keep in mind before proceeding?

The property has a massive 900+ sq ft attic with very tall ceilings that would make a perfect 3rd unit potentially grossing another $1000 per month. 

You don't change your business because of one potential threat.

I completely agree with @Ashish Acharya's points about the cost-effectiveness of a HELOC and the potential credit implications if it’s secured by your primary residence.

Or do you offer this type of funding on a transaction that could potentially take a few days, or even a week or two?
