Hi Rose- Few things to note about buying an investment property.1) Expect to be putting down 25%, as this is most lender's required downpayment on "investment" properties.2) You likely won't be cashflow positive unless you are putting >50% down, OR are buying in a C-class or worse neighborhood.3) Starting out with a condo or townhouse could be a great idea if you're just looking to get your feet wet with landlording- It is less maintenance than SFH or MFH, and you will gain invaluable experience managing a tenant.Aside from the financial challenges, I think it's great that you have the mindset to grow your portfolio.

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?

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.

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.

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

Here is 3 scenarios: conservatively projected low/medium/ and scenario 3 is actual recent net returns  (unlikely repeatable right now) I'm looking for alternative ideas to deploy $150-200k down payment on a much larger investment than a 1br house, so I can play the appreciation game as well as the income game.

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