If you can't, then yes you can bring your mother (or another person) onto the mortgage to help increase the income, but keep in mind, the lender will also have to take into account her liabilities as well.If you decide not to do that, or you still can't qualify with her added.

After I become a landlord for a few years, my mind is changed, I do not want to buy properties close to the college anymore, because my mindset is the same as @Alex Deacon now.

I think Millenials, my generation, have a different mind-set when it comes to a lot of things, including investing.  

Again, keeping in mind that this is a small duplex, as the landlord I'd rather not pay an extra $40 a month for standalone internet/cellular service.Which leads me to my question -- insofar as the submetering system could function through a tenant's cable internet service, is there any legal prohibition on including language in a lease to require that a tenant maintain such internet service for the stated purpose of monthly water readings?  

Most commonly done within 4 years.From there, They can enjoy the peace of mind of having the mortgage payments made without the need for a lengthy closing process and that they achieved a sale at or near the asking price.

I would personally just rent to someone that meets my criteria without a cosigner, but some people don't mind allowing a cosigner.

Also keep in mind that building up is cheaper than building out!

In our mind, we setup the company this way to do just that, avoid being double taxed by Business Income and FICA but our accountant is concerned with taking paychecks and not paying the Medicaid/SS out of it and then having to keep track of what side work is considered wages and what's not.

Keep in mind this is in Philadelphia PA.Thank you!

This is a great strategy but does not function here in Utah or Florida.
