I just tell them, they can apply but it is probably not worth their time and money because I wont be able to hold the property vacant for that long.

I feel that if I build new I wont have a issue for 10 yrs and I wont need to compete with other investors.  1.

There are much simpler solutions that wont cost you 18K. 

Many management companies archive or destroy old applications because they do not want to be responsible for SSNs getting out to identity thieves. 

Since you aren't looking until next year, you wont' be able to get a rate quote now, most likely not until you are under contract and they can lock that in. 

Are there any challenges or reasons why some of these tenants wont be able to pay through the software that I am not aware of?

All this as well as keeping an eye out for off market properties and sending them over to the client even though we really wont get paid until they decide to sell it if you are still their realtor by then lol. 

They're out there, you just wont see as many focused in the investment space as you will in the residential space. 

Food in fridge is from April this year and it basically looks like someone was half way through moving out and then something happened and so a bunch of stuff is still in house. specifically one room filled with about 10 burner phones, 3 tvs, personal clothes, mail, kids personal items and bunch of random stuff new with tags, etc etc. he also had pets which was against lease term. one of the rooms was used as a pet room completely destroying carpet and staining walls with urine etc. 

They wont have it either and they won't have their CDC guidelines or excuses.
