Also, as Luther mentioned, your potential local contact person (heck, maybe you can locate them on BP if you don't know of anyone where your rental is) can see if there are any issues with the unit or property as a whole. 

Rates are different depending on your location and I am not sure what you are seeing in Delaware but here in Texas we see 12-14% APR and 2 - 4 points due at closing.

Would you rather buy 1 property that is located extremely well (like a penthouse in the city centre) ?

Without knowing the specific location, I'd say C class is a reasonable classification. 

The listing is for 185k and has everything I’m looking for In terms of location and amenities.

Also, anywhere you're located, there're local REI clubs, join them and network with like-minded investors.

I am located in Union Co, NJ and have found 6 great deals of late but could not fund them...PLEASE HELP!!!

I also have a concern about the location.

The higher ends are full houses or apts with amenitiesProperty is located within blocks of a Cal State University so rental demand may be consistentCOC ROI is fairly low, but I’m comfortable getting a ~5% return on my first deal if it means that this is a learning experience.

The property located in Peninsula with attached garage.
