Most HMLs, depending on your and your partner's credit score and experience, only require 15%-20% equity/down payment from borrowers.

You can get a HELOC if there is equity in the property most likely, which there should be since you own it in cash, but you will just be decreasing your pay out and then may end up short in repair money, depending on how much it is worth.

This completely depends on what you are looking for.

I have to choose between a much cheaper market that I live in that is much easier to cash flow, but finding good renters could be more difficult.

Depending on how that conversation goes, post a 3 day for nonpayment. 

Not sure you really make more money.BRRRR would be interesting if you can find it.Flipping is competitive and brings in cash but not long term wealth.They all are great options, it just depends.

Even as a Foregin National you can still take out up to 75% Cash out depending on your citizenship. 

Selling would likely mean taking on new loans at much higher rates, reducing your cash flow margin unless the new properties are stellar performers.Transaction Costs and Taxes: Selling could trigger capital gains taxes (depending on exemptions) and other selling costs, eating into your net proceeds.

Essentially the only people who CHOOSE to move in the winter months are getting evicted from other people’s houses.

Depends on the person, but as a professional real estate investor it would be a no brainer for me.
