Those prices range from $800k-$1.5M depending on the specifics but the income increase is as much and the cost to own is slightly lower because insurance, maintenance, and utility costs do not go up linearly on these making a bigger margin for you.  

@Adriana Siu so you're going to offer maintenance-only services with no other services required?

Hoping for good neighborhood, good schools to attract low-maintenance family tenants. 

With the current market, I will not be able to make my required cash flow after paying all operating cost including mortgage, vacancy, property tax, insurances, maintenance cost, no need for a property manager because I can manage it.

Since all the expenses on the calculator were listed as annual, I took the monthly values on the realtor website and multiplied them by 12.I'm very confused on what maintenance costs should be estimated at, as well as what I should put for monthly rent.

Hi - I’m relatively new to the real estate game and am just starting to read multiple books involving this topic.I noticed a house being cleaned up two weeks ago, talked to maintenance people, and was in the right place at the right time to talk to the owner.

Some of those variables are the size of the park, number of vacant spaces, the number and type of park amenities, the age of the park, underground infrastructure age and condition, park location, size of the market, city water or well, city sewer or septic, other utility sources and whether or not they are direct billed, deferred maintenance, cost of management, and more.

And STR is much more involved with high turnover rates so you’ll not only need to post the listing but know how to keep it competitive so that you maximize bookings, of course, furnishing it, keeping supplies, restocked, cleaning, maintenance, And what about consideration to any local STR rules and regulations?  

I did not have your mentality at 21.I'd say you are headed in the right direction with the strategy you are considering - househacking.You'll be able to use a low-down payment option, learn to manage properties, create systems for managing maintenance projects, have your tenants pay most or all of your mortgage,... the list goes on.There will definitely be hurdles but like you said...you'll make it work!

Townhomes are a great start because they often have lower maintenance costs and better cash flow than single-family homes.
