That being said, I wanted to ask the community how other San Antonio buy/hold investors are generating leads. 

I'm about to have the lead certificate renewed and the rental certification completed after having done a number of improvements to the property and my question is this: is it possible for me to raise the rent (I'd be looking to raise it to something around $450)?

Do your homework, listen to podcasts, follow these leads and then research. 

Listsource is a great site for generating quality leads.

As they say, the first investment leads to the second and so on!

Any leads would be helpful .

It all depends on who your audience is.

I am looking to invest in a rental property that will produce good returns for years to come, any leads ?

@Joann LimNon-qualified investors taking out interest only loans is what lead to the market crash 10+ years ago.

Looking for a way to generate a lead in podio and automate the contract process all the way through emailing it out to seller or listing agent.
