That is why it is hard to get regular real estate loans on assets valued so low, the cost of the refinance makes it so you are paying higher than they can legally charge you percentage wise.

I charge more or the same per night as cabal front homes which cost at least double the price.

I only charge $500.

California charges a minimum tax of $800 a year per LLC, and more if you have gross receipts in excess of $250k.

In my market every PM would charge more than your projected $350/month (which I already indicated is not reality) to manage two average size units in a duplex.This does not mean cash flow does not exist. 

Owners were charged an assessment (several thousand dollars) in 2023 to put into reserves, as per the new rules after the Surfside collapse.

I would first wait to see what it is for gas and then charge them that portion (tough since weather probably nicer and not gonna be as high).Also you cannot go after the seller on this, but why did your inspector never turn it on?

So that means even many years down the line, after I've dropped them completely, and I decide to sell my property - they're going to come after me and charge me a months rent because they didn't sell my property.WHAT SCUMBAGS!!! 

and they charge per door and not sure if they even offer everything that I want. 

It sounds like a single family house where you will be living in the house(personal use).Therefore, you may not be getting the tax benefits you think you are.Consult an accountant.I am not sure why your sister would agree to this as well, she is losing $170,000 in this transaction and she faces the possibility of you increasing her rent.You also have to charge market rent or close to market rent or it is all deemed personal use.
