He only has 1 rental & isn't a Broker / Agent.

How could I target insurance claims tenants for my MTR?  For example, would I call the area home insurance companies to notify them of the available rooms?  Or something more creative?

The servicer may have their own fees, rules, and disclosures.Agent crosses a line to disclose rates, legal ins and outs, terms, and disclose the loan which even a broker license doesn't cover.

I am not aware of any pm co that will " custom build" pricing for a client. 

Advertising for vacancies is great - it syndicates across many platforms.It can be a little clunky and hard to learn for some things, but their customer support is excellent. 

I would also shop with a local mortgage broker as currently United Wholesale Mortgage is running a 125 bps special on Government refinances through the end of September meaning if you did go FHA streamline then you should be getting a rate of around 5% (borrower paid)4) If you havent asked, at 700K+ loan tell your lender you want to go Borrower Paid and you expect them to only charge a 1% origination charge fee.

At this point I had found I was pretty good at finding and managing tenants so I partnered with a real estate broker and started managing for other investors.

I would be curious to see where this exists, as it would have to be through a broker dealer channel in order for someone to get compensated for it, and most syndications require GP approval to transfer any position

I'm an insurance broker and I agree rates in FL are insane right now.

After hurricane Beryl hit, many were left without power for an extended period and I really would like to put my eggs into different basket/market if possible.I see that you’re a real estate broker in Texas yourself.
