My first purchase in CS was a fourplex.

I purchased my first rental property - a newer home in a high-appreciation market and neighborhood - with a business partner, and she and I have had the hardest time getting it rented.

Ultimately, I am looking to purchase/refinance with or without my siblin co-borrowing, then put an ADU on the home to rent out. 

Hello,  if I purchase a rental property in Miami this year and close under my name, and then transfer the title to a LLC the same year, do I need to anticipate TWO times the property tax hike for next year?   

Yes, as Lucia said, you should talk to zoning before going forward with the purchase.

Purchase price: $110,000 Cash invested: $40,000 This beautiful 3 Bedroom and 1 and half Bathroom house is located in South Acres Estates subdivision.

Are you purchasing them as distressed homes and rehabbing to hold, or purchasing something turnkey.

As an investor, you should only make numbers-based purchases.Also, agents are only transaction-based - if they make a mistake (or choose to take advantage of your naivete) they still get their commission check and can disappear:(So, a great PMC is often the best choice to start with, since they obviously know the rental market and they have to deal with whatever they help you buy, on a daily basis after the purchase!

Rent to purchase ratio is $4600/$430k = 1.07%.  

Are you looking to combine both your first mortgage on a rental property you own with a purchase of a new rental property where you are assuming the note?
