I have never used Mynd but Pete Nubig that runs the Houston Market is top notch.  

How is private money lending currently influencing the real estate market?

Hello Misael, I would do a thorough market research to verify that you can get the rent increase you want, you might find out that the market is oversaturated with rentals.If you are trying to raise the rent $100/mo, 1 month of vacancy ruins your rent increase for the whole year.I would list the property for lease 45 days before your tenant's lease expires, if you have your property priced right you should get some applicants before your lady moves out.

Purchase price: $300,000 Cash invested: $65,000 Sale price: $455,000 This house needed a full renovation to compete in the challenging Austin, TX housing market.

The key is to know the market including the supply and the demand in the area. 

@Sylenthia Boswell I hate to break it to you but its going to be really difficult to get deals without having some money to spend on marketing/skiptracing/cold calling.

I have sold one in 40 days and others are on the market. 

Hello there was a huge vacuum in the market and you know what they say about that..... 

Are they only in Houston, or other markets, too?

Obviously if you can do the BRRRR method do it, but that is a lot easier said then done, especially in certain markets.
