In 10 years, you've effectively 10x'd your initial out of pocket, not including the pay down from the tenants. 

Here’s my strategy and the issue:Current Strategy:Buy a property for $200k with cash.Refinance after 6 months to recover $150k, leaving $50k in the property.Use the recovered $150k to invest in another property, but I need to save up more money to repeat this process.Alternative with Hard Money:Use hard money to buy properties worth up to $800k.Refinance them later to recover my initial investment.For the hard money scenario, obviously I wont be buying them all at once, but rather buy a property worth 350 -> refi -> get HML -> repeat, until my money has ran out.However, hard money can’t be used for cash offers directly, as it’s typically a loan.

If the property is sold at a loss, can you unwind a 1031 to off set the gain on the sale of initial property?

Probably will take you longer to ramp up, but at the end of the investment say 2-3-5-7 years hopefully you still have your $50,000 plus some cash flow, but hopefully even more the GPs have 2x or 3x your initial investment.   

The method consists of marketing/publicizing the guru to create demand for the initial “free seminar”, where a pitch is made for a low priced $99 - $199 weekend workshop.  

A strong labor market can lead to wage growth, which further fuels inflationary concerns, making the Fed less inclined to cut rates in the near term.However, many recent jobs reports have been revised downward after their initial release.

A cash out refi should get you a good appraisal value and the windfall that might work better than a HELOC, but it depends on your initial rate.

It may be a good time to sell when the market is experiencing high demand, rents have stagnated or decreased, and your property has substantially increased in value compared to its initial purchase price.To decide if it’s the right time to sell, compare the increase in rental rates with the increase in property prices.

I prefer tenants pay using electronic ACH transfers through apartments.com and in those cases payment is considered made when they initiate the transfer even though I don't receive the money for days afterwards.
