Crawlspace foundation houses in Miami

[Yoni R.]

I just put an offer in on a house that is a crawlspace foundation and is located in Miami. I am looking to buy it as a rental income property. Most of the other houses in the neighborhood are regular foundations on the ground. I liked the house and definitely liked the roi which is around 14%. My friend by chance spoke with another investor and told him about the house that I am buying and he said that he stays away from crawlspace foundations. I wanted to get some more info from the bp community to see what they think about houses that are not solid ground foundations and what issues I should be aware of. Thanks!
