I faced challenges with unexpected repairs during renovations, but having a contingency budget helped mitigate these issues.

Stick to budget and focus on tenant-friendly, durable finishes.

I typically provide that as a starting point and then assess my situation/budget for the BRRR/and timeline for my next move with the investment. 

There's options here for all budgets and experience levels. 

The trouble was finding a contractor within budget.

Half way through thought, we were over budget and went back to our hard money lender to close out the cards and finish the project.

As a small business owner in a previous life, I found the bookkeeping super daunting, despite my love for numbers, budgets, & just data in general! 

Use full HYSA budget to fund ~$30k house hack funds (about 12 months)3.

I know in my projects, there are times where I will have 5-8 trucks/vans in driveway on street during certain phases. 

We went way over our expected budget - by far our worse budget miss ever (remarkably we were only 0.5 week over our 2 month timeline).Using my rule, take the estimates and double them then add for lost occupancy and that is what I would be seeking or the owner have the work done using licensed contractors and do the work, take the risks, and suffer the vacancy costs.If you purchase having to do the work and your appraisal can handle it, the credit at closing is superior to price discount.
