They will let you know what you can and can't do without a permit and what you are able to do yourself within the scopes of those permits.My concern is because this is a rental, if you do anything that is not to code and the tenant reports it, you will likely have some much bigger issues to deal with.Given you note this is major rehab, I tend to lean to hire most, if not all, out.

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.
