Type of construction materials for the build(block/metal frame/wood frame), separate utilities, finishes, tech, cleaning crews, any tips and tricks would be HUGE! 

And i found launch control but the minimum is $500 a month, but they use cross-referencing data across sources to find the most accurate contact information by using a person's name and address to find their phone number, real address and email by accessing public databases, phone number directories, credit reports, utility bils, public tax records, and social media profiles. this is waaay expensive for me as a beginner. what do you suggest or if anyone has any suggestion I'd greatly appreciate it.??

I've been thinking a lot about Florida and I believe it's a great state for future potential investments such as purchasing and renting out (utilizing the BRRRR Method Of Course).

Specifically, I’d love to hear about best practices for managing shared spaces, screening tenants, and setting up house rules.Additionally, I plan to split the utilities among the tenants—any advice on how to handle this efficiently would be greatly appreciated!

.), but the bedrooms are regular keys, as @Jonathan C. mentioned for the front door, the unit is set up to send me an email when the batteries are low. i also have another student rental ( 8 rooms, 2 entry, 2 units + utility room) one master key and each bedroom has its own key that will get students in the entry, there unit, and there own bedroom. had a locksmith do that one. cost me a few hundred dollars with keying and supplying the locks ( 13 total ). i like both setups but may look into the landlord locks again for my 3rd student rental i just purchased.

There are quite a number of things that can make utilizing an FHA loan more difficult such as more barriers during appraisal, appearance of low qualification/little cash, typically longer closing period, likely higher interest rate, and PMI cannot be dropped without a refinance if 3.5% down.That said, just chain 5% down conventional loans, and make sure your duplexes pay for themselves.
