I think it also helps them demonstrate their comfort in qualification and interest in the property.

I feel much more comfortable and knowledgable going into this deal!

I entertain the idea for a little bit and have had some extensive conversations with this person, and as much as they are trying to say they are not a scammer and it's a legitimate investment, I'm not comfortable with the situation and will not be doing business with this person.

I would be banking on appreciation over time but I am comfortable with that.

Air Conditioners are the devices which require regular care and maintenance and if taken precautions properly can make one's life very comfortable.

Maybe that is something you are comfortable in dealing with, but starting out, you may not be.

It will take me  a few hours and a bunch of edits to tell my story, so here is a short Quick reply, i started real estate straight out of high school,in the toughest parts of south central Los Angeles no car no money i will say this if you learn how to communicate and talk to sellers in a humble sincere effective manner you will be surprised what a seller will be willing to do to sell their home to you, in my experience it is not who offers the most money it is who makes the seller feel more comfortable, im refereeing to FSBO's, reo's etc was not popular back then but foreclosures were on fire, i was pretty good at talking and adapting to homeowners in distressed i'm very big on what i call the "like factor" so i was able to arrange terms that some of you would not believe me if i wrote it in a post, my point is yes you can buy with zero money (if you have the knowledge and know how) it is several ways to get a deal done when you have no money.

I would be more comfortable with a mortgage I could pay in its entirety without tenants, and having a tenant would just be a nice help on my mortgage (therefore allowing me to put the money I save back towards the property / maintenance).Am I being overly cautious or am I being a smart investor?
