Skilled Handyman... But new to flipping houses.

[Trevor Simko]

I'm new to this forum. Let me pre-apologize for the lengthy post. 

I'm a college student and I've been working part-time doing rennovations for a few years. (Flooring, painting, basic electrical, landscaping, etc.) I've saved up a lot of cash lately and I've been looking to obtain some properties, either to rent or resell. 

Since I've been working only part time, some of the jobs I've done have just been under the table cash transactions. So my proof of income isn't great for getting accepted for a loan. I'm thinking of starting a business for my rennovations jobs, build credit and proof of income. And hopefully with time get accepted for a loan for a house.  Is this a good idea? If so, any tips please? 

Thanks, Trevor
