So we closed on Sept 3rd and we got a nice big fat check for 14k!!!

hi marcus. yes, filters need to be changed often. in fact, i recommend at least once a month, depending on the location of your furnace and cold air return system. that being said, here is my experience and expertise. ( i just competed getting my certification in furnace repair). the purpose of the cold air and fan are to circulate the hot air to the area where heat is needed. but the purpose is also to cool the heat exchanger in the furnace as well. the heat exchanger is a sealed system of pipes that the heat created by the burners heats up. the air from the fan/ cold air return blows passed the heat exchanger to circulate the heat to other areas and to cool the heat exchanger. if the filter is clogged, no air gets past the heat exchanger and consequently, the heat exchanger will overheat and get damaged. i have personally seem the heat exchanger with massive holes in it due entirely to a clogged filter. it is highly unlikely that your heat exchanger inside is full of dirt, but the fan and area around the heat exchanger could be filthy

We are finding that many of the contractors are fat and happy. 

android has an app called "burner" that you can create different numbers with any area code. then u pay for theem as you go.no idea if it's going to help u in what you are doing.

Here is how you do it. put a fat bonus for agents who sell two or three or more properties as a package, and make sure you do not post that info on the Remark Section of the MLS  that everyone sees it.

I am a buy and hold guy of 13 units (SFRs, condos, duplex, ADUs), with fat equity given when I bought, and think I have wrung out all of the value-ad plays that can be done in this SD market (or maybe not?). 

I think it is very unprofessional for one contractor to badmouth another and that guy is a big fat jerk for doing so!!  

Personally I would keep looking and keep this condo on the back burner.  

The biggest disadvantage would be in the time it takes to perform a member draw that you are going to burn, er I mean spend to keep the lights on and the family fed.We use different bank accounts based on who is lending us project money.

I am dedicating alot of time developing leads and my "other" job has taken a back burner.
