Duplexes and 2 units only get a carve out from AB1482 rent control if a unit is owner occupied prior to tenant occupying the other unit or less than 15 years old.  

Im back on bigger pockets after a long hiatus; trying to start up a STR from a owner occupied 2 family home with intent to advertise on furnished finder. 

Occupied with inherited tenants or vacant?

I have been receiving wrong accommodations and prices because because their personal life background, they were incapable of screening me nonetheless I had good credit and clear profile, they were just discriminating on the basis of their scarce preparation to human situation and so by their presuppositions, that's probably also illegal.You cannot say landlords are to be forgiven because they are doing a needed service, instead it's for that very reason they have to admit their fault and change their way of behave: if a business owner is occupying the market with bad practices and wrong services it's likely they need to leave their place and let others settle in who can operate the business correctly, their even more such of problem if their services is basic, but it's quite absurd it's on me to explain you this.Landlords would have to better understand theirs are affairs on a public market, it's not private or personal matter, and as so they have to behave buy clearly stated rules or face immediate consequences.

Good bad idea before I depart - have you considered an owner occupied option?

There in fact is no law in Texas saying you cannot have a HELOC on a non-owner occupied property.

As @Patrick Drury mentioned- the West Side does not have any POS areas (besides Lakewood, but it's only needed for previously non-owner occupied/rental properties) Something else to consider in Cleveland proper is Lead Safe Testing ..

I owner occupy the home, renting a room to a friend at $650/mo, and the lower unit rents for $1850/mo - total rental income of $2500/mo.

When you say your house hack phase has passed, are you saying you DON'T plan to occupy a unit of the 4-plex?
