Calculating Max Purchase Price (Bay Area)

[Jerome Hawkins]

I'm getting ready to make an offer on a property listed at $299k in American Canyon, CA (Bay Area). The ARV,based on some pretty solid comps, is around $405k plus. Will likely use a hard money lender and a private lender/partner to fund the deal. I'm trying to figure out how to accurately and carefully run my numbers to come up with a good maximum offer. I get that I have to figure out purchase, holding, and selling costs, but I'm wondering how best to determine those numbers with enough confidence for my market area. Any solid guidance/answers appreciated! Thank you!
