What are my ADU loan options?
ADU loans don’t have a single one-size fits most financing mechanism, but we see each of the following options used to finance ADUs:
HELOC / home equity loan (home equity line of credit)
Home equity loans are essentially second mortgages that lenders give to you because you have equity in your house that their willing to lend against, even if you have a first mortgage
A HELOC (home equity line of credit) - this is typically a line of credit based on the amount of equity you still have in your house
Cash out refi - in this situation, you’re refinancing your first mortgage and the amount above the amount above the pay-off amount for the original loan goes to the borrower
Personal loan - this is an unsecured loan that is based on your strength as a personal borrower. Amounts tend to be smaller, rates higher, and payback periods shorter than secured loan options
Chattle loan- these are essentially loans that are secured by the manufactured home, but not the land underneath. They tend to be shorter term than conventional mortgage with somewhat higher rates.
RV Loan - these only work for RVs or often tiny homes. They are secured loans, but typically have worse rates than home mortgages
Construction loans - these are typically administered by banks and credit unions and will usually require them to a. approve your builder b. review your plans and budget and c. have an appraisal done to make sure the after build costs are consistent with their LTV (loan to value limits). These are typically short term interest only loans that become or get financed into long term loan programs. They are really structured for new construction but can be used for adu’s sometimes.
Government programs - these programs vary a lot in scope, but often aim to help lower or middle income people afford to build ADUs. Often they have small loan amounts, but very competitive rates.
