welcome @Jose RiosYou always have the option to rent out your rooms in your SFH to generate income as well ! 

I am the head of a single-income household of 4, and after accidentally discovering BiggerPockets and Robert Kiyosaki, I've decided to move my family into my in-law's place (from Garfield to Bergenfield) in order to stop paying rent and begin saving serious cash for investing in the near future.I would like to start off with a duplex/triplex/fourplex as primary residence while collecting decent cashflow.

Plugging numbers form local property managers into maps and spreadsheets, analyzing home costs vs. rental income vs. population growth and a few other factors.

It is located in an area I am very familiar with, in a high income neighbourhood on a quiet street near parks, schools and all other amenities.

Thanks to good timing (which I didn't really realize) the market was very good to me allowing me to pyramid up to much better income.

I've read some about buying the properties within both types using mortgages and how the income is treated differently due to some profits coming from your money and some coming from the banks. 

Keep in mind that most banks will require you to have 2 years of rental income before they'll allow you to count that income when calculating your debt-income ratio.

As more and more of that happens, run down areas can be revitalized providing a safe place for those with less income to live.Good luck and learn as much as you can.  

I am looking at a mobile home park in CT with the following details:- 18 spaces fully rented for $455 / month (received as an HOA - owner does not own the mobile homes but rents the spaces and includes utilities as part of the $455 fee)- Separate unit on the property:- 3 offices rent for $400 each / month (currently rented)- 1 apt bedroom for $800 / month (currently rented)- A storgage shed that gets $1400 a yearTotal Annual Income = $122,400Total Annual Expenses = $92,701They are asking $1.2M for this property, and I am new to this type of investment.

I also think the price have a lot of room to appreciate due to the relative affordability of housing relative to household income in Charlotte.
