Sold lots of houses.

You will be house hacking, so ask yourself "Is this somewhere I would like to live?" 

@Victor PengWhen buying a single-family house, there are typically two agents involved: a seller’s agent and a buyer’s agent.

I know we could get houses for cheap, I am just not sure what the rental market is doing out there.

A friendly introduction can set a positive tone and help build rapport.

Setting up networks of agents, contractors, and wholesalers in various markets. 

I am starting a park that will end up with roughly 20-25 lots on plot of land that's roughly 20 acres (including an existing 4/2 house).

House hacking is a great way to get started.If you PM me, I'll send you my Chicago house hacking guide if you want it.

The tenant broke the lease and moved out and left a messI sent the message that the secutity deposit is not enough to cover the expenses after the tenant moved out to the last known address of the tenant (which is my rental house)A friend went to get the mail and its sitting there in the mail box.So, the tenant has not left any forwarding addresses and has not forwarded the mail.What should my friend do with that mail?

Feel free to reach out to one and set up a consultation call.
