I imagine it would also have a lot to do with your long term goals in real estate.

I have used both TSP loan and HELOC to purchase investment...I certainly thought the ROI from real estate was better than relying on highly fluctuating stock market. 

You can most certainly make more money with higher occupancy in your short-term rental.2.

Many Realtors will suggest purchasing a property using a FHA Loan, to reduce your out of pocket money.

I financed the acquisition of the land with personal and private money.

Since you said you are selling your building I’d argue you already have been a real estate investor.

I'm still new to real estate investing but I'm open to feedback  @Jade FrankIt really depends on your long-term goals.

Are you a real estate professional?

@Zack Whiting Id change your mindset of real estate investing being a hobby and making it a more serious part of your life.

The biggest mistake I see is investors bouncing between different marketing methods too soon, without giving one a real chance to work.Since you already had success with mailers before, doubling down could be a strong move.
