One of my tenants is a co-worker with a kid & a cat.

I needed a vent fan put into a powder room to get a CO this week.

are but you said they are attached and if they are attached I doubt you could ever split them and sell them unless this is a condo association or a co op situation.

First of all commissions are negotiable.Second a majority of commercial brokerages offer a co-op because it is just GOOD BUSINESS and in the best interests of a seller to do so.Some brokerages and there are a few on the commercial side have a very bad reputation for dirty dealings with other brokers.

I bought into a co op once that encouraged investors to buy and a few years later they prohibited the sub leasing of their apartments.  

We have been actively searching to purchase a co-op since last August (which is most within financial comfort), and the combination of outrageous prices + fierce competition has dragged this process on for over half a year.

he also wants to invest. he wanted me to sign a co wholesale contract or something. i said no. but it was funny he couldn't decide if he wanted to be an investor buying/selling for himself or a broker buying/selling for other people. 

I have spoken to a few agents and they recommended I get a co signer or partner to help with my income since I have low income but a high credit score.

A few RE agents have recommended that I get a co signer with more annual income so I can take out a higher loan and open up my options.

If you are unable to qualify for an FHA loan, I'd suggest a co-applicant (parent, friend, other investor) or searching for a seller financing.Good luck.
