I doubt he'll be able to quality for a loan (VA) with just his income. 

As of this week we have secured the land.

I've helped people with SBA loans to purchase real estate for a business, but for buying rental real estate, the DSCR loan is a much better option.

We're willing to live almost anywhere in the greater Sacramento area based on what we can afford, provided of course that the property is in a decent neighborhood that has a good chance of attracting responsible tenants.As for budget, I believe we could get a conventional loan for properties up to $600k, but my strong preference is to find a distressed property (or seller!)

I know that interest on the acquisition loan can be included in the cost basis since it’s inventory.

All this does is report their payments to the credit bureaus like how your credit cards or car loan company reports payments to the bureaus.  

Any advice on securing financing for potential buyers would be greatly appreciated.Personal Experiences: If you’ve owned, sold, or rented out a geodome, I’d love to hear about your challenges, successes, and any tips you might have for marketing or managing this type of property.Thanks in advance for your insights!

That is a common arrangement as well, that can be done after the loan has closed, too. 

Let's use that as an example. 20% down is $43,000 plus lender loan origination fees, closing costs etc is going to push you over $50,000 cash out of pocket.

Quote from @Devin James: Im currently learning this lesson with New Builds that have taken twice as long to complete than anticipated.....Finishing a Real Estate project ASAP is critical because...1) Holding Costs add up quickly- Loan Interest- Property Taxes- Insurance2) Investor Capital- Our financial projections are dependent on how fast we can turn our investors capital.
