If you are a DST investor with Crew Enterprises a.k.a Versity Investments a.k.a NB Capital with suspended monthly distributions please PM me. I am aware of the properties at Wolf Run in Reno NV, Inspire on 22nd in Aus...

I don't see an exact location in the OP, but if this is even remotely considered rural, you are adding another LTV reduction. 

Usually when a landlord cannot find qualified tenants but are getting a fair amount of inquiries there's an underlying real estate problem and the qualified tenants simply do not want to live in that location.

Since then I have located the area where they entered and sealed it off, however I'm having trouble killing the ones currently living in the attic.

How many bedrooms does the property have and in what zip code is it located?

I’d love to hear more about what you’re targeting in terms of property type and location.

Long term $ can range from 6's-10% range depending on all types of factors - LTV, location, unit count, debt coverage, borrower strength, full doc or lite doc programs, etc..

I personally would not invest in detroit as historically its not a appreciating market and for cash flow and I invest primarily for appreciation - I go off the location location location mantra. 

Where are you located in New Jersey? 

Location is irrelevant, there are great QIs that can be remote to you.
