Secondly, how do you finance these units? 

Most of the time, we resolve the situation in less than three months through cash-for-keys agreements, court mediation, or by creating enough pressure that the tenants decide to leave on thier own.We currently manage over 700+ units and flip about 20 multifamily properties a year, the majority of which have inherited tenant problems.

Duplex have different zoning that may permit additional units.

@Chris Clarkson, having a partner can complicate things for sure if you're not united on direction. 

I've found some construction companies that specialize in ADU (Additional Dwelling Units) conversions/construction in SanFrancisco and San Diego but not as many in LA. 

My first questions are what price range are you trying to buy a property in and do you have a home already in the United States?

So if you're not raising rents to at least $2700-$2800 if the value of the units are truly at $3000, then why get a tiny house. 

Ask how many units they manage and how much experience they have.

If we rent the unit at $1,425, I have an estimated monthly cashflow of $302 (rent at $1450, cashflow is $325) I DO include vacancy, repairs, and cap exp in my Box2 Expenses.

Eventually the park gets heavier and heavier with POH units.
