It’s deduction times your marginal tax rate. 

If I was starting out, I would focus exclusively on renting to college students and avoid all the grief I went through with Sec. 8 and marginal tenants with crappy jobs.

My degree is my margin of safety & a high paying skill necessasy in our future.I am an international student who’s adjusting his status (getting my green card) this year.

The advantages of speed and streamlining operation technology can increase lender margins, or help keep interest rates and borrowing costs low.

Cash flow today (though it’s nice as a buffer and margin of safety...) and more focused on acquiring great located assets that are lifelong holdings.

But to me if your commercial lenders are asking for what you said they’re asking that may mean the deal itself is kind of marginal.

But since your mortgage is fixed your profit margin should increase.Secondly, over the life the loan you will pay more interest. 

I also launched a customized T-shirt company and that has taught me much in the way of product development, managing operating costs and expenses as well as marketing, profit margins and other cool things you're not taught in school.

I feel with purchasing a little bit cheaper of a home and renting out to tenants that are not my friends, the margin of profit may be a little bit larger.  

The model is here to stay, but regulations, margins and even platforms may change.
