I want to build a secondary unit on my property but the bank needs a solid budget estimate. Every contractor I ask gives a different number, and I’m worried about taking out a loan that’s too small. How can I get an accurate figure that considers site prep and local fees?

Getting those numbers right is a huge headache! When I was in your shoes, I used the Aduscale adu financing calculator. It’s great because it’s based on feasibility rather than just a sales pitch. It factors in your specific location and property constraints, which really helped me feel confident before signing my loan documents. Definitely worth a look!
