There's pockets here for good multifamily, but the best play is to do some value add work to the property.

So, go with a good solution on the deadbolt.Screw a lockbox in a wall near the door for an emergency physical key.Find a locksmith that can rekey the doors between tenants - put ALL locks on the same key.Most electronic locks warn you when the battery is getting low.

From my experience working with over 400 investors, I’d recommend starting with house hacking—ideally a fourplex if you find a good deal, but a duplex works too.

Im glad you're doing good. 

Good luck!

Honestly looking at your situation I'm not sure I would recommend you do the taxes yourself,  change of accounting method (F 3115) isn't easy for someone that hadn't done them before these online software companies make things seem easier than what they are, they are good for less complex situations. 

If your interest payment is $8,125Your stocks have to make a dividiend of about $11,000 of which you would prolly pay 15% to 25% in federal / state taxes / NIIT.Assuming you will make a 10%-11% return is not guaranteed.You will also feel good about having a paid off property(relief).Furthermore, your credit score may go up with a paid off property.Best of luck!

But you should have a good idea of when that will come due and if you can finance it.

My issue is, it's been almost 3 months and I haven't be able to get good tenant applicants.

Is this is a viable strategy, is there a good resource to learn more about this?
