So MY idea is to buy now before prices could go up and then refinance at a lower rate if they reduce significantly (which I don't expect them to reduce significantly (-2%) anytime soon.

Im happy to network, share/exchange ideas and help others get started.

You need to have a pretty good idea of the value of properties you look at to be successful. 

Have you been able to get proper directions / guidance from his team to buy your first rental property?

I am not aware if there's such community in miami alread.My idea is to create a group of people with the same objectives, where we can share our experiences, learn from others, help each other grow or start in this journey.

But the actual costs that you mention to "properly market your home," what are the costs specifically?

Use this equation to evaluate how much to offer on a property:Max offer = After Repair Value x 70% - Rehab BudgetDo you homework on comps to get a good idea on the ARV. 

My first time was a househack deal and I had no idea what I was doing.

Another idea would be to visit other construction projects occurring in your area whether it's residential or commercial and gain information on the contractors they're utilizing. 

If I understand your situation correctly, you could structure a Tenancy In Common (TIC) deal where each of the separate LLCs owns an undivided interest in the replacement property, as tenants in common.These deals need to be structured properly and you need to have an attorney familiar with 1031 exchanges involved to make sure it's done properly.Also, if there is a lender involved, that can complicate the matter as well.It's definitely doable, if you have the right professional help while you're doing it.Feel free to write if you have any questions about this.
