Each HDFC has its own income cap, but most are based on a multiple of the Area Median Income (AMI) often 120%, 165%, or 185% of AMI.
As a general rule, your total household income has to fall below that limit. The number depends on how many people are in your household and what the building’s regulatory agreement specifies.

Buyers typically submit two years of tax returns, recent pay stubs, and a few months of bank statements to verify eligibility. If you’re close to the limit, it’s smart to have someone review your documentation before applying — a single line item (like a bonus or freelance income) can make a big difference.

Most HDFCs that we deal with do not have resale or asset caps, but when they do, the details are written into the building’s regulatory agreement with the city.

The income cap limits who can buy it’s meant to keep ownership affordable for NYC households.

The asset cap limits how much in total assets (savings, investments, etc.) a buyer can have and still qualify. This prevents very high–net-worth buyers from purchasing homes intended for affordable housing, even if their income is technically within limits.

The resale price cap (sometimes called a maximum resale formula) limits how much the apartment can sell for — often based on the original purchase price plus approved improvements, or tied to an indexed formula connected to AMI.

If you’re buying, it’s important to confirm whether the price you’re paying reflects one of these formulas or the open market — it can have a major impact on both eligibility and long-term value.

You can absolutely finance — but not every lender understands or works with HDFCs.

A handful of banks do, and some have dedicated programs for these buildings. They’ll want to review the regulatory agreement and the building’s financials before issuing approval. We have great relationships with these banks and are happy to put you in touch.

That said, not all buildings qualify for financing. HDFCs that have poor financials, overly restrictive policies, or complicated regulatory agreements often have trouble getting loans.

It’s also worth noting that HDFCs tend to attract a good number of all-cash buyers. One of the keys to success is working with a mortgage broker or bank officer who’s done HDFC loans before it can make or break the deal.

Again, it’s very building-specific, but most HDFCs do have a flip tax. In many instances, it will be a percentage of the profit, though that can vary widely.

It’s part of how the building stays affordable long-term. Flip taxes often help subsidize your monthly maintenance fees and capital improvements.

Before you make an offer, your agent should confirm exactly what applies in that building.

Usually not, at least not sanctioned by the building itself. But it does happen, and in some instances, HDFCs have formal sublet policies.

That said, HDFCs by definition require owner-occupancy, and subletting is either prohibited or very limited (for example, a one-year exception for hardship or temporary relocation).

If you have no intention of living in the apartment, an HDFC is probably not the right fit.

They tend to be much lower and that’s one of the biggest advantages.

HDFCs often receive property-tax abatements or reduced assessments from the city. But remember, every building is self-managed to some extent, so maintenance fees depend on how well the board budgets for repairs, insurance, and reserves.

It’s always smart to review the building’s financial statements to make sure the low numbers are sustainable. We’re always happy to help you with this.

Nothing. Congrats on the raise!

Once you’re approved and living there, you’re not re-screened annually. The income cap applies only at the time of purchase.

That said, the idea behind HDFCs is stability (not flipping) so even if your income grows, resale restrictions and flip taxes still apply when you sell.

It depends on how you define “investment.”

If you’re looking for quick appreciation or a speculative play, this probably isn’t it. But if your goal is affordable homeownership, stability, and equity growth over time, then YES! It can be a fantastic long-term investment in both your finances and your community.

We’ve also found that a good number of HDFCs are significantly undervalued. Often this happens because the brokers representing them don’t fully understand their value, or because there’s been an internal shift in policies or the building’s financial health that the market hasn’t yet priced in.

Part of the value we bring is helping you identify an HDFC on the upswing and avoid the ones headed in the other direction.
