The bright side is that you have a really good interest rate, my interest rate on my current primary residence is actually what made me decide to hang on to it. 

I am renovating a residential and I am taking down walls.

Shop around for a broker that will let you if you’re hitting a wall with your current - brokerages have different thresholds for “risk”, different minimum loan amounts, strategies they offer/specialize in.

Also, as we were clearing out the finished basement, using ”finished” loosely, the wall coverings hid a structural crack around the entire foundation.

If I start having to dig into walls and the sub - floor I will almost automatically put an extra 5-10% in rehab costs for unexpected items since that is when you will typically find something that would be better addressed now rather than later. 

The house had the front door kicked in, furnace was stolen and wiring was stripped out of the walls. 

@Jaron Walling Thank you so much for taking the time to reply to my post! 

I was on the fence on getting an attorney’s review and decided to start with the forums to see if there is low hanging fruit pertaining to the strategy. 

Don't leave things hanging out there for months.

Over the time living at the property we renovated the garage walls and added a sub panel, finished the basement adding a full bathroom, painted the cabinets, added more hardwood flooring to the house (kitchen and 2nd floor), replaced the appliances and fresh paint everywhere.
