The Financial Library

However you got here, it's organized.

Every question lives inside one of six connected disciplines. Lead with the outcome you want — the structure is just how we keep it all straight.

Deal Analysis

Don't fool yourself.

Underwriting a property before you buy it — revenue, real operating costs, DSCR, and the margins that survive a soft month.

Explore →
Financing

Use debt wisely.

Capital and leverage — how debt changes the economics, how lenders evaluate you, and how to choose (or decline) financing.

Explore →
Entity Structure

Build on the right foundation.

LLCs, ownership, liability — the structural decisions that are cheap to make early and expensive to fix later.

Explore →
Bookkeeping & Reporting

Know what's really happening.

Chart of accounts, platform payouts, cleaning and turnover costs — and how to produce numbers you can make decisions from.

Explore →
Tax Strategy

Keep more, legally.

Depreciation, material participation, the 14-day rule, and the elections that quietly decide what your rental costs you at filing.

Explore →
Wealth & Exit

Make today's decisions create tomorrow's freedom.

Scaling, refinancing, recapture, 1031 exchanges, and the exit — turning a rental into long-term wealth.

Explore →
Why it's worth your time

The more you explore, the clearer the financial side of your rental becomes — and the easier it is to make decisions with confidence.

No jargon, no upsell — just the financial thinking that separates a rental that quietly works from one that quietly doesn't.

About

About Builders Finance

Founded by Matt Nunn, who has spent two decades working with the financial side of real estate businesses. It exists because STR owners run real businesses with real financial complexity — and almost everything written for them stops at nightly rates and occupancy. Everything here is educational; Builders Finance doesn't take individual clients.
