I am no longer eligible for traditional bank financing, so I am working on securing hard money for my next property.

Keep in mind getting it to current HUD standards will still not make it qualify for traditional lending if you end goal is to sell it. 

It can actually be riskier (investment wise) as you are not getting a traditional check every month, but added responsibility that you will hold onto the lump sum throughout the 3 month tenancy to accommodate for repairs, mortgage payments etc... 

So a Joint Venture offer needs to be double an offer for a traditional sale to make up for the tax differential.  

I haven't used hard money, but I hear there is no holding duration requirement; some traditional loans require you to hold it for 6 months or 1 year. 

Is there anyway to bypass any of the requirements? 

I will also get another roommate who will also sign an agreement (I’m house hacking), but I think I need them to live with me for a year for it to count.Please let me know what a lender would include for gross income for traditional for non-traditional.

are you doing cash right now or traditional hard money at typical 70-75 / 90 LTV/LTC?

Definitely be careful, as most nationwide brokers will incorrectly rate you for traditional property management insurance, which almost always applies to LTRs and specifically excludes STRs in the fine print. 

Find someone that will loan you the money or partner with you on it that is non traditional like an investor that buys directly at foreclosure auctions in the area.
