When I questioned them about it they only mentioned the leak. 

What’s a rule of thumb for Utilities (Water and Sewage, Electric, Gas) per door number?

All my places have a gas and charcoal grill. 

(Gas, water, electric)While I don’t feel comfortable going the same route in the case they would take advantage of high heat or lights on 24/7.I want to have them pay for utilities, looking around online and even a few rentals in the area, it seems like it’s common to have the landlord pay for water.

A few of the pictures make me think it was flooding rather than a leaking pipe or roof.  

Attempting to close on a house that had a serious leak for almost 6 days.

Could you have a leak somewhere?

@Ivan MiletichGood morning, illl to answer your questions based on what I’ve done and in Los Angeles county might be different for Orange County. 1- the easiest and fastest way to do an ADU all depends on the where your utilities located so attached and detached can both be easy and fast as long as the sewer electrical water and gas are located near by that is going to determine how expensive the project will be the rest is easy.2- All ADU’s need foundation but that’s not too expensive to do if you don’t have foundation. 3- I’m waiting on some blueprints right now for a triplex because of COVID plans are taking longer than usual4- as far as I know yesOther than that I think the most important thing is TIME you need should focus on is starting the ADU process, as far as for me it takes about 2-3 months for blueprints and for the city to issue the permits.

Then they live about 2 more years and it never leak again.

I plan on a minimum down payment of less than 5%.Property management: - 10% of the rental income Utilities (Electric): - Since I will be living in one of the units, I estimate around $80-100 for electric for myself, and the tenants would pay their for their own utilitiesUtilities (Water and Sewer): - $50 a month should cover water and sewer (tenants pay for their utilities)Utilities (Gas): - $50 a month should cover gas (tenants pay for their utilities)Utilities (Garbage): - $60 a month should cover garbage (tenants pay for their utilities)
