I sent a warning to pay by two weeks-(stupid i know), but he did & its been on time ever since (4 months now).  

Several people warned me about this.

The tenants are expecting this notice, because I've given them warnings, and two neighbors and one contractor have complained about things like trash in the yard, dog poop in the house.

It seems like I have much to learn and am so thankful that you took the time to warn me of all the potential risks and your willingness to share your experiences with me.

@Rocky GriffinAsk if they are a direct lenderAsk for referencesAsk for all fees upfront Ask if any additional fees at closingAsk if they do any rehab fundingGenerally, look for an alignment of interest between yourself and your HML - which means as little upfront as possible and on-going relationship.Any application fee or any upfront fee for reviewing your deal is typically (not always) a warning sign.Good luck and let me know if I can help.

You will definitely start to pick up on the warning signs after learning the hard way a few times. =)                   You can be spending your time showing them a lot of low end properties, writing below market offers, irritating fellow Realtors and their Clients with insulting offers. 

Be stern if you must because as a newbie I will have occasional tunnel vision and stubbornness to get the deal done no matter what.

I also send out warnings in a month when the electricity is higher than expected for a particular month even when not close to allowance limit. 

The bubble is always 18 months away :)Here are similar pundits who predicted crashes, with excellent numbers and reasoning behind them, over the past five years. 2013: Denver Post: “Buyers Caught in a Price Squeeze”CNBC: “Housing Market Already Shows Signs of a New Bubble”2014: New York Times: “The Bubble Is Back”Fortune: “Why the Housing Recovery is over, in four charts”2015: CNBC (Again): “Housing today: A ‘bubble larger than 2006’”National Review: “We’ve inflated another bubble; count on the crash.”2016: CNN: “Housing bubble fears have returned”MarketWatch: “The Seeds of the Next Housing Crisis have already been planted”2017: Forbes: “58% of Homeowners Think The Housing Market is Set for a Correction”USA Today: “Hot Housing Market Could Cool in 2018”2018: Bloomberg: “This Rare Bear Who Called the Crash Warns Housing is Too Hot Again”I think that if you are afraid of a bubble, you'll never invest, and will surely lose.

Any tips, warnings, or knowledge from experienced commercial investors would be graciously appreciated.
