Triplex Deal (Need Help w/ Evaluation)

[JP Findley]

I am a Realtor in DFW and have been considering multi-family investing for years. I have a client who has been renovating a property for the past year.  She did an amazing job and is willing to sell it to me for $300,000 (no commissions). 

Here's the deal:

1. Purchase Price - $300,000 (I'll be putting 25% down). Monthly mortage is roughly $1400 per month (this includes taxes and insurance).

2. The property is older - but is literally like a brand new property. It has new everything... plumbing, HVAC, metal roof, flooring, bathrooms, kitchens, paint, cedar beams, cedar shutters, vaulted ceilings, landscaping.... everything! It was a $150,000 renovation. The entire complex is also being sold completely furnished with high-end furnishings throughout... subzero refrigerators, bed linens, high-end furniture, etc. 

3. Rent for each unit is projected to be $1500 per month ($4500 total).  I think that's conservative.  It is also surrounded by a number of a number of major corporations who have thousands of employees. I expect it to rent quickly, but I don't know the area well, so I could be wrong.  It definitely feels like the nicest rental in town.  Most rentals in town are in the $1000-$1300 per month range for older, non-updated 1-2 bedroom apartment spaces. 

4. Property tax rate is 1.4%

5. I plan to manage the property myself for now. May be a mistake, but it's literally like new. I figure I can find a GC in the area to go over when I have issues. 

6. The current owner was offered $5000 per month from one of the nearby corporations to use it exclusively as their rental property for their executives / employees. This was 6 months ago while the property was being renovated. She is not sure if the offer still stands. Trying to find out. This is one of the reasons I believe the $4500 per month is conservative. 

So.... is this a good deal?  It feels like it is a homerun, but I am a complete novice in personal real estate investing. I know there are a lot of ways to get burned on a deal like this that I am sure I am missing.  Any advice? Does this sound promising? Any help would be tremendously appreciated.
