Guarantor letter

Hi im a single mum trying to get a rental house but after months of no luck my dad has offered to go guarantor to see if that will help, but were both stuck on how to write a letter for me to put in with applications stating his willing to go guarantor can anyone help a template or sample letter would be great if not just some tips

Just tell prospective LLs that your father will be a guarantor for you and ask for a seperate application for him (since they will want to screen him too). This is common in many situations for various reasons, poor or no credit, young applicants, couples just starting out, etc. The LL will screen you and dad, then give you the guarantor letter for him to sign at the lease signing.
