One had a client's cold water line crack in the middle of the night and flood the basement.

PROS: a) minimally invasive; b) individual unit and in-unit-zone control; c) high efficiencyCONS: a) given Chicago's extreme cold snaps in winter, they cannot be (according to code) used as a "primary" heat source. - One possible solution would be to keep the existing boiler/baseboard system for backup and/or use in extreme cold (possibly triggered by an outside temperature sensor).

I recommend working with an investor-friendly agent who focuses on cold-outreach methods like cold-calling, cold-texting, etc to bring you off-market deals.

Everyone knows how hard it is to convince someone through cold-calling that you aren't wasting their time.

You could start with the basics cold calling, knocking, and social media.

The seller can go cold at any minute.

I'm looking to pick up my first property and I'm trying get a good deal on it, so I've been cold calling distressed sellers in the Houston area. 

@Joshua Biondi  You don't need a 24 hour handyman but you do need a 24 hour HVAC service if it gets as cold in winter as here.

propstream or some other list service filter and make a list use a list service to contact owners via cold calling, mail marketing, texting etc Once the owner is contacted, get the condition of the house, pictures and get a contract signed 

Since I've never dealt with previous tenants, I'm looking for some advice on the best way to move forward...Unit 1:- Studio Apt- I did a walkthrough last week and spoke to the tenant; he mentioned the only issues he's had in the past year and half is that the cold comes through the windows- He and the owner both confirmed that the tenant is month to month and paying $750, but so far the owner has not provided a lease.- The owner did provide proof of payment, and rent is confirmed $750, but always a few days late...Unit 2:- 1 BR- There was a language barrier, she didn't speak english, and I think she was afraid to open the door so I didn't get to tour it.
