If you are concerned it will be too hard to find a renter, lower the price and rent it for three months, then place a new tenant at the higher rate after winter.

Those are addressed on this one.

@Christian Pichardo not a fan of Tom Cruz as he exaggerates everyting about his success to sucker people in:(Let's address several issues:1) Buying on recommendation of "Guru": what guarantees did they give you about performance?

Just enter the address of whatever property you're looking at and the site calculates the market rents 

I have a few concerns that I wanted to get people's thoughts on. 1 - Selling a quadraplex 10-20 years down the road seems like it may be challenging as the market for that type of asset is small.

One of my original mentors was PRO lease option on the purchase side, however I never felt  peace about it.I was always concerned what if something happened to the original seller and they did not cooperate when it came time to exercise the option. 

With the increased competition, it’s also crucial to prepare your listing to stand out and work to address buyer objections prior to going on market.

Once you have the address tracking down the owner would be the easy part.

The final straw was when my property went into abatement after an inspection, due to the property management company's failure to address tenant requests for the exact items that caused the issue.

After looking into it more, I'm concerned about potential tax implications and legal issues, such as piercing the corporate veil.
