The three big challenges are financing, zoning, and room size. 

@Robel Nessro if you're majoring in something like business management/finance/business, you'll certainly learn a lot of skills that you can transfer to numerous branches of REI...So, that type of college degree can give you multiple points of leverage (it can help you understand REI, while also helping you understand how to operate other businesses, while also qualifying you for W2 jobs--so, you can reap multiple rewards and have multiple options just from one college experience--that's great!)

If you and the property qualify for traditional financing that should be far and away the best financing possible. 

Financing PathwaysConventional Cash-Out Refi: Ideal if you want predictability.

.: When you are new, looking for lenders & considering Fix & Flip, BRRRR, or rental, as a buyer, I’d ask the owner/seller to be one of my private lenders with creative financing.

We can finance one of these properties via traditional 25% down investment. but I would like to buy all 3 and I believe I can get a significant discount if I can get all 3. below are the property values and returns using the full asking price,  5 years rental history, quoted 6.99%IR, utilities, maintenance, etc. and a summary of my financial position. any advice on how to finance these to maximize returns other than negotiating down the price?

For private seller finance lenders, how do you track the payments and loan amount? 

I have done a few owner finance deals over the years. 

You have three potential challenges:1) Most banks & credit unions won't put their HELOC, or any 2nd mortgage, behind owner-financing.2) Same lenders won't recognize the equity difference between purchase price & appraised value for at least 6-12 months.

Is a real estate agent really necessary if you are planning to offer Owners financing?
