Source-of-funds mistakes
1. Undocumented source of funds
The #1 issue — down, closing & reserves all need a clean, seasoned trail.
2. Moving money at the last minute
Large unseasoned deposits raise flags — fund your account early.
3. Under-budgeting cash to close
Forgetting reserves on top of down + costs. Calculator →
Documentation mistakes
4. Submitting untranslated documents
Every non-English doc needs a certified translation.
5. An incomplete foreign credit picture
Missing the international report / bank reference letters.
6. Passport / ID issues
Expired or mismatched ID — verify names match across documents.
7. Dribbling documents in over time
A complete package up front closes in weeks; a trickle drags for months.
Planning mistakes
8. Choosing the wrong path
Defaulting to DSCR when full-doc prices better (or vice versa) — compare.
9. Using a non-specialist lender
Most loan officers rarely handle cross-border files — use a specialist.
10. Ignoring the LLC-vs-personal question
Decide ownership structure before closing.
11. Taking the first non-QM quote
Make specialty investors compete.
