Employee management is not a strength of my husband (and he happily admits it!).  

That takes serious strength.

They're doing this because you've trained them to believe it's ok to do so.Or, if they're great tenants otherwise, they might just be paying you as they get paid (bi-monthly). 

My equity in the property is 80%.The property is in north east, San Antonio, its a 5B, 2.5 bath, 2784 sqft, Lot 6969 sqft  15 minutes from downtown and 5 minutes from the Airforce training base .

Several thousand dollars of training is insignificant relative to the profit it has brought us.

For instance, I suspect vacancy might be a little higher based on the train tracks running directly behind the condo.

I would check with your lender to confirm if 0% can be used for 3 and 4 units...they might require 5% down.SFR investment with rehab can also be a great way to invest in real estate. it just depends what are your strengths and goals and which strategy will best serve you.buying a home a year is normal for some. depends on what your goals are.Id think of it like planting a tree: being 25, time is on your side. if you have a solid income with healthy DTI, I would suggest taking advantage of it by house hacking small multi in A/B market and let father time be your friend.

These are professionals with additional training and a stricter code of ethics.

If they start asking for money for more mentoring and training to the tune of $5000-$25,000 or more, run.

Use your strengths.
