Plus one of the benefits you'll be interacting with lots of people - sellers and buyers and may by chance come across your future partner to jointly buy MFH.  

One benefit for me is it allowed me to buy a newer property in a great area with top schools, where a SFR in the same area was beyond my budget. 

However, there do seem to be solid benefits as well. 

However, with the normal wear and tear/ usage of the two main entry doors to the units foyer area, we have had more than 5 service calls on the locks (for batteries, lock mechanism not functioning, etc.) and both front door Locks have had to be replaced once already and I am thinking it is time to use a different Door Lock method. 

What are the tax benefits?

The main issue with SFRs compared to multifamily is scalability.

You can find the exact chart if you google "Texas veteran real estate benefits" but if you have a disability rating you can be exempt from paying a certain amount of money (thousands) in property taxes.

:) But I’m brand new at this and just educating myself for the first time... so far the main criteria to finding a ‘proper deal’ I’m aware of is to make sure you but your property at a discount. (20% - 30% discount seems right but I’m sure practicing this is much more difficult than it sounds.) 

It would just be an insurmountable task to go out and find every single code violation existing in any given jurisdiction and that is the main reason code violations exist seemingly everywhere.

I chose what i thought would be a conservative number for 2 main reasons: there are only a few exterior pictures in the listing, which led me to be believe the inside may need work and that the landlord is not on good terms with his/her tenants.
