Contact DealUnderwriter

DealUnderwriter is a small, focused team building underwriting software for residential rental investors. Every message goes to a real person who underwrites deals — not a ticket queue. For support, feedback, or press, email hello@dealunderwriter.io or use the form below. We typically reply within one business day, and always within three.

What we can help with

Underwriting and metric questions

If a number in the tool doesn't match your own spreadsheet, tell us the inputs you used and which metric looks off. Cap rate, cash-on-cash return, DSCR, NOI, expense ratio, GRM and the 1% rule are each computed server-side from a fixed formula set, so we can walk you through exactly how a figure was produced. Most mismatches come from a different treatment of vacancy, capital expenditure reserves, or whether management fees are included in operating expenses. If you would rather test the calculation yourself first, open the free rental property underwriting calculator and change one input at a time.

Pro billing, invoices and cancellations

Pro subscriptions are billed monthly through Stripe. Email us from the address on your account if you need a VAT invoice, a receipt with a company name, a plan change, or help cancelling. Cancellations take effect at the end of the paid period and you keep Pro access until then. Refund questions are answered in full in our refund policy for Pro subscriptions, and billing terms are set out in the terms of service.

Privacy, data export and deletion

You can ask us at any time for a copy of your data, a correction, or full deletion of your account and saved deals. We action verified requests within 30 days, usually the same week. What we store and why is described in the privacy policy and GDPR rights page. If you email a deletion request, please send it from the account address so we can verify ownership without asking for extra personal data.

Bugs, feature requests and market coverage

Bug reports are the fastest way to get something fixed: include the page URL, what you expected, what happened, and the browser or phone you used. Screenshots help. If you want a metric, loan structure, or market that we don't cover yet — short-term rental modelling, seller finance, a specific DSCR lender overlay, or a city missing from our rental underwriting city pages — say so. Feature requests from paying Pro members are prioritised, and requests that repeat across several investors usually ship within a few weeks.

Partnerships, guest posts and press

We work with lenders, agents, and property managers who want their process reflected in the tool, and we occasionally publish guest analysis when it is backed by real deal data. We do not sell links or publish sponsored posts on the rental investing blog. If you are writing about underwriting software and need screenshots, figures, or a quote, email us and we will send assets the same day.

Response times and support hours

We answer email Monday to Friday, roughly 09:00–18:00 Central European Time. Messages sent over a weekend are picked up on Monday morning. Billing and account-access issues jump the queue; feature discussions may take a couple of days because they get a proper answer rather than a holding reply. There is no phone support — writing forces both sides to be specific about the numbers, which resolves underwriting questions far faster.
