I recently obtained a couple of quotes for foundation repair on one of my rental properties.

Has anybody sold a property owner to owner (owner financing)?

These properties often have systems with about ten years of life left and are situated in neighborhoods with appreciating property values and rental income.The cash flow from a property largely depends on your down payment.

We are in the hard money lending business for commercial properties - with loan sizes from $500k to $5 million.  

If that were true the various real estate niches would have almost unlimited competition and profits would head toward 0.  

What would be the best use or strategy with a 75K HELOC to fund an investment property? 

This either provides opportunities to invest in more real estate, rehab a property(s) or for personal use.You can also sell low performers to do the same.

For me it's that simple but I'm sure folks with more properties or properties in different areas have better systems than I do!

Once you come up with a entry price point,Overall strategy and goals, then it’s just about finding the best available property on the market.

This involves purchasing a property with 1 to 4 units using an owner-occupant loan.
