Heeeey BiggerPockets FamilyI am a verrrrrry new multi unit investor (experience in single family home investing and renting out to the Section 8 population) with the goal to buy/hold properties for cashflow.

That should be your focus.Personally if you have one mortgage already that is negative cashflow I would be hesitant to buy rright now, especially in canada where from reports their housing situation for pricing is far worse than the US on affordability and just like US, people think prices can only go in one direction but reality is they are moving in the opposite direction.

You can mail them a letter saying that you are a cash buyer and you like to buy their property.

Can I keep my current house as a rental and still buy the house hack?

There are many institutional investors from Wall Street that buy single family homes.

Most of these are a standard SFH residential loan, but for business purposes so they normally require a 20% down.Not as easy to get, but there are 10% down 2nd home loans that people, including myself, have gotten in the past.Comps are based on SFH sales, unless you are buying Multifamily of 5 or more doors.

I am currently looking to buy my first property in the DFW area (Plano,Frisco,Allen) and am looking to connect/hear from others. 

They also depend on what loans you qualify for and what homes are available in your area.Whatever you do, as a first time homebuyer, make sure you buy a house you can afford and that your monthly payment is as low and affordable as possible.
