I have done some preliminary research, but have found it hard to really find anything concrete in terms of requirements.

My preliminary research shows that it is a decent area and renters make up about 27% of the residents there.

Most title companies will give you a preliminary title report if they have a relationship with you.

No one told us this until we did the investigating and talked to the right people.Think like the government...

I am still trying to learn the area, so I am not sure about which locations in Houston are best for looking for small multifamily.After some preliminary searches, it seems that most small multi are in lower class neighborhoods and not sure if that would be something I would want to house hack.

There is an investigation and they find this: "That was my first wiring project in my life.

It's common/normal to inspect a house with residents in it.The mold was revealed during the inspection...it's pervasive on the bathroom floor, which means a lot of water and/or a long time period, and would normally lead to a much deeper investigation for damage in the rest of the house as water easily travels. 

I get calls from wholesalers all the time and they are simply horrible on the phone disorganized and have no preliminary information on my property.

We have these processes in place to discover issues such as these and protect you as the buyer.I've had to hire a private investigator in the past to have previous owners sign a new deed to correct a conveyance. 

I'll hire someone at a much higher rate (even a private investigator) depending on how much I have at stake.
