My suggestion is to buy a property worth more than $1M since anything cheaper for 4-plex will not be high quality.

there is tremendous demand for inventory right now, and as you have already found high prices and high rates have hurt cash flow. 

I agree that pricing a rental too high is a classic mistake than can make it sit, but don't you think encouraging landlords to rent quick will make them compromise on the vetting of the tenants?

Some hard money lenders lend at pretty high LTVs, leaving little equity buffer to protect your principal.

If prices are too high people will just go elsewhere.

I HIGHLY recommend you have a conversation with an attorney. 

Maybe the tenant set the thermostat high? 

Much better as a short term acquisition strategy for flips IMO but always a high-risk strategy that should not be practiced by anyone who doesn't have the liquid capital to pay off the loan if needed.

I got the Discover It Secured card in high school and used that to build up my credit. 

If you are using it to buy a turnkey property which needs to produce cash flow to be considered a viable deal how does buying turnkey(Little to no cash flow) combined with HML(High interest only debt) make alot of sense financially?
