Running a fancy Class A downtown luxury apartment is far different than a 50 year old building in a low income area. 

Let's say below is my yearly depreciation2021: -$10,0002022: -$10,0002023: -$10,000As I had no other passive income I couldn't take the depreciation, but in 2024 if I have a passive income can I take the depreciation from all the previous years or only the past year?

On top of the NNN/CAM allocation you also want to factor in annual rent escalators and vacancy assumptions.

This step is about generating income from your investment.Refinance: Once the new properties are stabilized (occupied by tenants and generating income), look into refinancing them based on their new, improved value.

Passive income here I come 

Quote from @Arthur Schwartz: From your PITI, how much is the monthly or annual pay down on principal? 

I own a recently renovated duplex in the DTLA/Westlake area and I have been searching for a local property management company with experience in lower-income, multi-unit zoned neighborhoods.

Half of US renters are “cost burdened,” meaning that they spend more than 30% of their income on housing (rent + utilities).

I can add my mortgage, retirement accounts, income, bank accounts and credit card accounts.

My understanding is that Rentalizer overestimates both income and costs.
