If this mystery person bought an SFR in Los Angeles in 2009 I'm sure they've made more than 200% if you look at their down payment and juxtapose that with the increase in equity.

First I understand I need to get my finances in order before I even start looking at houses so I dont have a ton saved up but I do have over $100k in equity in my house. 

In just over 3 years or so, you've managed to gain 400k in equity.

.$72K in equity based on a opportunity value of 10% is worth $600/month.

I also have a vacation home worth about $600k in another state, I have about $375k in equity in it, would the local bank be able to help with that too?

Thank you @Becca Summers right now I am still getting my down going I have about 50-75k in equity in my first house but I want to get rid of some credit cards that we used to do some work on my main house then I will use the equity and whatever cash I had down to make a huge down payment on my first rental to make it as risk free as possible I could already afford about a 2k mortgage on top of this one that I have but I don't want to restrict myself cash wise anymore then I have to on my first property 

Hit a snag in my investment goals :Scenario ;I have 85k Saved to invest I made 6 figures in 2018 Have 60k in equity in my existing rental property in Nassau county New York Good Credit BUT ....I lost my job last month and I’m concerned lenders will give me a hard time for not being employed, although I do have a small business that is brining me at least $3000 a month in profit.

Financing: We have less than six figures in equity in our primary property and we have retirement $ tied up in a 401K.

From what you are saying, it looks like this property will have 80k in equity when you go to sell it, with only 40k of investment.

This leaves 20% or more in equity in the p[roperty, thus PMI is not necessary.
