In the commercial & private money world its all fair game and case by case.Use of credit cards to purchase properties to acquire/capture equity, create, cashflow, provide additional tax shield/benefits against your income, and improve your real estate investing venture is definitely one way to go about it but it should not be the sole method since there are risks like many have mentioned above.If you're using business cards (linked to your FEIN - federal employer identification number) and it doesnt report to your personal credit then it might be more prudent credit wise because your Fico scores won't tank when you max a business card out versus a personal credit card (drop of 80-100 fico pts temporarily till you payoff).So with prudent timing (funds seasoning), knowledge of how to maintain your ficos so you still qualify for your cheaper conventional money, and how to use the cards to purchase can definitely expedite your REI journey.Most people I encounter would not have the know how to do it correctly as I see plummeting fico scores, in ability to qualify, and many other issues with using cards to invest on a weekly basis.Best of luck,

I know this an old link so rather than offer my insights relative to the questions already posed, I thought I would bump the link and offer to answer any questions that remain or resurface.

Links below to articles that explain some of the possibilities.   

@Sara Holda Here's a great link to the city that outlines a lot of the laws regarding STR in the Nashville area: https://www.nashville.gov/depa... 

They can ACH it, walk in to a branch with cash or a personal check, etc.I know a lot of people find these third party vendors convenient, but to me it just puts another link in the chain between the tenant's payment and my revenue. 

The post is old, but it has several articles links in it about the neighborhood over the last decade.: https://www.biggerpockets.com/forums/517/topics/53...Old North Dayton is a C+ area, working class neighborhood. 

Do you have a link or something to this "certification"? 

New investors spend way more time crunching numbers on a spreadsheet instead of seeing every home on the market (you can go to Open Houses if you aren't linked with an agent yet) to get sight reps.2.
