How Cash Buyers Calculate Offers in NJ (The 70% Rule, Explained Honestly)

February 20258 min read

You got a mailer, a postcard, or a phone call: "We'll pay cash for your home as-is." The number they quote feels low, but is it? Understanding how investors calculate offers is the single best way to evaluate any cash offer you receive — and decide whether taking it makes sense for your situation.

The Foundation: After Repair Value (ARV)

Every cash buyer calculation starts with ARV — the estimated value of your home after any needed repairs and renovations are complete. This is what a buyer would pay for a fully updated version of your property on the open market. Investors typically estimate ARV by looking at recent comparable sales in your area.

The 70% Rule

Most NJ real estate investors use a formula called the 70% rule:

Maximum Offer = (ARV × 70%) − Repair Costs

Example:

  • Your home's ARV (fully renovated value): $500,000
  • Estimated repairs: $60,000
  • Maximum offer: ($500,000 × 70%) − $60,000 = $350,000 − $60,000 = $290,000

The 30% they keep ($150,000 in this example) covers: holding costs during renovation (typically 3–6 months of carrying costs), their profit margin (typically 10–20% of ARV), selling costs when they resell (agent commission ~5.5% + closing), and risk buffer for cost overruns.

Why Offers Vary So Much

Not all investors use exactly 70%. Some use 65% (more cautious), some 75% (competitive market). The repair estimate is also investor-specific — their contractor may estimate differently than yours. This is why getting 2–3 offers is important: you're not just comparing prices, you're comparing assumptions.

What "Fair" Actually Looks Like

A fair cash offer in NJ typically lands at 65–75% of ARV minus repairs. If you're getting an offer at 55–60% or lower, the investor is building in extra margin — often a sign of a wholesaler who will assign your contract to another investor for a fee. If the offer is above 80%, double-check their repair estimates — they may be low-balling repairs to make the offer look better.

The Convenience Cost

The honest way to think about a cash offer: what is the "convenience cost" — the difference between what you'd net from a traditional listing (with time and effort) versus what you'd net from a cash sale (today, as-is)?

In NJ, this gap is typically $50,000–$150,000 on a median-priced home. Whether that's worth it depends entirely on your situation. For some sellers — an estate, a foreclosure deadline, an out-of-state owner, a home with major structural issues — it absolutely is. For others, it isn't.

Red Flags to Watch For

  • Pressure to sign quickly ("this offer expires in 24 hours")
  • Refusal to provide proof of funds
  • Very long inspection periods (sign of a wholesaler seeking to assign)
  • No earnest money deposit
  • Verbal-only offers — get everything in writing
