However, be prepared for limited inventory, higher competition, and possible compromises.

I have a HELOC on my Texas primary residence and am considering a house hack for my next purchase.

@Tina Artigliere@Alicia ProkosFor these Quest Solo 401k plan account holders, what is essential is to find a new Solo 401k plan provider who offers a Solo 401k plan with the service and features that the account holder needs such as Solo 401k loans, alternative investments, Roth and Mega Backdoor Roth Solo 401k contributions, 5500-EZ & 1099-R preparation and filing, etc.The process entails restating the Quest Solo 401k plan where the Quest Solo 401k plan documents are replaced with the Solo 401k plan documents of the new Solo 401k provider. 

Here is some info: SF STR FAQAssuming the info is up-to-date, it must be your permanent residence (you must live at the property for a minimum 275 days a year), you can rent unhosted a max of 90 nights a year, you need a business license, and you need to pay the city $925 for a STR certificate.

One of the great things about having multiple residents per property per year is that you can iterate faster than with an LTR.

Also, did you have any other loans (ie student loans, primary residence mortgage, etc) when you took on the $25k? 

Yes. the original lender probably will not but a new lender may- there first question is gonna be what is your exit strategy so be prepared to answer that question.

Quote from @Richa Wardhan: Regular lender financing, we have paid off 70% of our mortgage on the primary residence so we were loaned money without any issue. 

.- Depending on your budget, do you want a small condo or larger residence?  

Therefore that's why you void the contract and re-write the contract with the additional tenant and his terms and conditions as well as Qualifications and requirements for them to reside there.
