It just was casually mentioned by the remaining female tenant at some point. 

I have a banker who has considered doing only 10% down if there's other buildings in your portfolio that can support the remaining 10%.

It's a trip for sure :-)There are many REI opportunities in different markets - markets in the Midwest and Southeast of the country are great - where not only are the purchase prices reasonable for most RE investors, but the homes are turnkey (new builds or completely rehabbed homes, tenant ready, systems 10 years of life remaining on them, property management teams in place) with appreciating home value AND appreciating rent.

The skills and strategies remain similar, but you’ll need to familiarize yourself with local markets, regulations, and financing options, which can vary a lot depending on the country.

If your startup costs are over $55,000, you lose the immediate deduction, and the entire amount would have to be amortized over 180 months (15 years).Here’s an example to clarify:•If you spend $7,000 on startup costs (such as attending BPCon, legal fees, and market research), you can deduct $5,000 in the first year and amortize the remaining $2,000 over 15 years, starting when your business is officially active.

The upside for the investor is guaranteed returns, while the upside for you is that any profit above the agreed interest remains yours.Another option is a profit-sharing model, where the investor funds the deal and takes a percentage of the profits after the sale.

And use the remaining as a down payment on something that cash flows. 

Loan Term and AmortizationCommon Term Lengths: Loan terms for seller financing vary but often range from 15 to 30 years to keep payments affordable for the buyer.Balloon Payment: Many seller-financed deals include a balloon payment due in 5 to 10 years, at which point the buyer would need to refinance or pay off the remaining balance.
