Buy a house with a bad septic? Can't be replaced until Spring '22

[Jamie Derasmo]

I'm looking into a SFH to either BRRRR or flip. (I know I'm putting the cart before the house with this question but I'm still running numbers and market info). The septic failed it's inspection and will need to be fully replaced, I received a quote for $30K which is accurate to the system needed and high water table area. The issue is engineering and permitting will take approximately 2 months and by then it will be winter. All companies have said Spring 2022 would be the estimated replacement date due to frozen ground (property is in Rhode Island). This would only be my second investment property (other one is a BRRRR that is still under renovation right now so my money is tied up in that.)

Question 1: Would this be a property you even looked at right now knowing that it won't be complete until next summer?

Question 2: A hard money loan does not seem feasible due to the length of time I'd have to hold the property. What do you think my best loan option would be to not incur too much interest/expenses? I'd like to wrap the full renovation cost ($110K) into the loan but I don't have to if that would make getting a loan harder. 

Any advice would be greatly appreciated!
