It is easier to bullet proof a small duplex than a house.  

Should I discuss some bullet points and do a small contract between me and the buyer or is there a standard contract for such that we can agree up on terms prior to handing the deposit to the title company?

All standard commercial mortgages include DSCR, calling an assisted living facility mortgage a "DSCR loan" is like calling a home loan a "DTI mortgage," or calling a cup of coffee a "caffeine coffee," or calling a gun a "bullet gun." 

I’m not creative when it comes to interior design and wondered if I should bite the bullet and hire a professional to establish our interior design theme.

-should i just bite the bullet and pay for the new HVAC systems?

My question is, do I bite the bullet and add mini splits?

I think we dodged a bullet, we tested TenantCloud and didn't like the fact that you had to signup for multiple accounts just to get online payments.

Then I hung up the phone and laughed to myself for a long time, glad I'd dodged that bullet.

Nothing is bullet proof, but a good maintenance process helps.
