Before taking the dive though listen to a great apartment course/video/cd (if they still have those) 10 times. please don't skip this step!

Yes it still does exist but not so easy to find and usually is easier to achieve on C/D class housing which means you're going to work for that money.

Drive around a bit as well - there's still a lot of regional players in billboards if one is operating in your market chances are you'll do better with them. 

Never heard of them before....but your typical real estate "mentoring" guru will invite you to a free 2-3 hour session, and convince you to come to all day on Saturday or 3 day weekend course for $299-$399, when you are at that course, they'll convince you to be a Big Dog player for full on mentoring at $15,000-$50,000.   

I built the property in 2005 each unit is 4 bedrooms 3 bath  in Houston Texas I just spent the weekend masterminding with serious players in the group home space. 

Another great resource is Linkedin, reach out to players in your area and offer to take them out to coffee or lunch.

If your goal is something longer term or diversification based, maybe treat the down payment like a CD with a big potential bonus that'll pay out when you refi when rates drop, or 1031 exchange into something bigger in 10 years. 

CD earns say 5%.

You may find that what you own already works just fine, or that the yield on 400K is less than current CD rates.  

If this is a TRID (conventional, FHA, or Non QM) loan the lender issues an initial LE and a CD.
