How to Structure the Deal to Protect Your $20KIf you’re willing to cover the $20K arrears, here’s how to protect yourself:Option 1: Secure Your Funds with a Lien or Escrow AgreementUse an escrow account: Deposit the $20K into escrow with clear terms—if the assumption is denied, the funds return to you.Record a promissory note & lien: If the deal falls through, this would give you a legal claim against the property to recover your funds.Option 2: Sub-To + Wrap While You AssumeSubject-to deal: Take over the existing loan payments before assumption approval, securing control.Escrowed deed transfer: The seller signs the deed into escrow only to be recorded after assumption approval, ensuring they can’t back out.Lease option fallback: If the assumption is denied, consider a lease option agreement until another solution is found.Option 3: Negotiate a Seller Financing HybridAsk the seller to carry a small second note for the $60K equity gap at favorable terms.Use your $20K as a down payment, structured as a secured loan against the property.3.

Some/many lenders don't like a 2nd mortgage behind their first (like the skin in the game), however there are both bridge or permanent financing options out there allowing you to leverage anywhere from 90% CLTV - 100% CLTV, but don't expect good terms...

I have a few other options - feel free to shoot me a DM if you want more specific contact info, etc.

Do all your due diligence upfront (see if you can get an inspection done before submitting an offer)On the lending side a DSCR loan is an option.

No other loan option comes close to that. 

With good credit, you can leverage business credit options.

Pacing yourself is key, especially as you get hands-on experience managing maintenance and tenant dynamics.Since you have a strong W-2 income, you're in a great position to leverage creative financing options as you grow.
