Use the security deposits you hold for collateral.

My question to you is which trajectory do we take to secure our next home/rental property?

All buildings close to the beach requires piling on the first floor then you can either add 2nd or 3rd floor depending on your business plan.You can reachout to real estate agents that are predominant in the area to provide you with short rentals income report.Let me know if you need any help or info about building ground up.

I ended up hiring one of my LTR tenants as a house manager to handle all of the cleanings, turnover and provides my local eyes and ears.  

I'm having difficulty finding insurance providers in Central Texas. 

We added value by repainting interior, new floors, new roof, resurfaced the pool, added a fence for privacy, upgraded the landscaping, sealed and painted the exterior, added central A/C with new unit, upgraded the irrigation system, added gutters, added security cameras, added hurricane proof front and rear doors.

Good Evening,I have a question, so I bought a rental property with tenants in place, The previous landlord didn't require them to have a security deposit, How would I go by with telling them that I required a security deposit, also they pay at the end of the month for the month they been on, I would like to have them pay rent the month before. so for example have them pay the rent this month for the upcoming month and so on, how would I go about doing that.

They value properties equipped with smart home features, such as automated lighting, thermostats, security systems, and voice-controlled assistants.

If your goal is assume a loan, I would offer the lender some sort of compensation as they are generally only paid if they write your loan, which is not the case with an assumable loan, as the current servicer will be underwriting and providing the new loan.  

Based on the info you provided, the other 2/3 don't have the same mindset as you and you aren't going to agree on what to do or how to do it.
