Will it be difficult to secure 3.5% down financing on the second home since I will have gotten a mortgage loan a year prior? 

The receptacle in the 2nd floor hall bathroom is loose and needs to be properly secured to the junction box.

We are about to finish an identical property next door to this one and rent it to more baseball players.

New Roof, All new Doors, paint, Totally remodeled office, kiosk, Renter's insurance and security system.

I have a few friends in the established sector in CA and the biggest complaint they were having on purchased facilities would be the established security that comes with the building. 

I also plan on installing key phob entry for the lobby, and some security cameras in the common areas to better secure the property and help the tenants feel safe.  

No real contact info (there is an info@ email buried somewhere) and even though the search is fairly polished some of the pages are sketchy looking and the subscription links aren't even actual CC forms or secure.

Not that you'd expect to default, it's obviously the worst case scenario, but that is a whole heck of a lot worse.An alternative to refinancing is a line of credit secured by the property, a HELOC. 

Added security might do the trick. 

What these gurus never seem to mention however is how someone starting out is supposed to secure commercial lending when the requirements are so much different than residential.
