BRRRR – Rehab Question

Hi David,
I love the Bigger Pockets podcast and blog! I’m reaching out because I’m a 22 y/o homeowner looking to get into real estate investing through the BRRRR method. My degree/work experience is in accounting. I did public (tax) for a year and now work in industry. I’m currently working on my real estate business plan and wanted to ask you about rehab. I am actually pretty handy and savvy and could handle cosmetic renos myself (updating bathrooms, etc.). I’ve gained a decent following on IG and TikTok through this. I’m not quite there yet, but once I get my Instagram following high enough, I hope to partner with brands to bring reno costs down to what would essentially just be contractor labor for things I can’t do or don’t have time for by promoting their products.
Okay so now… getting started with rehab. I intend the start out with a hard money loan to purchase my first property. Would I adjust this to include purchase price + rehab costs if I am unable to pay for rehab out of pocket starting out?
My best,
Madelyne Rose
