One example would be the office sector being hit hard with defaults.

Housing is just the perfect example of this.

Example: You have a 3-Family Building that has 3bedrooms 1bathroom on each of the three floors - 9Bedrooms 3Bathrooms Three Living Rooms Three Kitchens.

One example of the hot U.S. economy: wages.

If i sell my SFR rental for $450k and equity is, for example, $200k...Can i invest 100k into a new SFR worth $275k and invest the remaining 100k into a sponsored DST or TIC (which deals are usually multiple hundreds of thousands of dollars?

This is a fine example of where to research out of state investments as the housing prices to purchase are still reasonable and low (not like California where I am and entry level house SFR is a million dollars). 

Examples:44109 (median home price went from roughly 50k to 125k in 8 years)https://www.zillow.com/home-values/77009/cleveland-oh-44109/ 44102 (median home price went from roughly 30k to 120k in 8 years)https://www.zillow.com/home-values/77002/cleveland-oh-44102/ 44106 (median home price went from roughly 100k to 200k in 8 years)https://www.zillow.com/home-values/77006/cleveland-oh-44106/ It has the highest rents on average in all of Ohio for major cities and the median home value is not even in the top 3.

For example, require a minimum FICO score of XXX, gross monthly income X times the rent, and verifiable income for the last X years.

I am in Orange County, California, and a 4-unit in Newport Beach with one unit being a 3/2 for example LTR would not bring in 7K gross income on that unit.

An example would be owning a franchise.
