Im located in Phx,Az and its common here to still see empty dirt land in prime areas of city, as an example, my father who knows next to nothing about real estate purchased a 7k sqft gated dirt land  in the city 3yrs ago for $35k cash, was planning to invest in it but it was too much hassle for him so recently he sold it for $140k .What's a good way to find good deals on empty dirt land  in the city or close by, does mls offer this search option.

You can pull out up to 80% of the value of the home, depending on credit score and property location.

Sometimes, charging LESS rent actually earns you MORE money in the end!

Is the rent paid in full on time, every time?

I have found that if its a good enough deal to flip , its a good deal to keep as a rental , sometimes better , as a rental you do a quick repair and cosmetic update and rent it out , and in maybe a couple year it has appreciated , you then do a remodel and sell and you have made much more 

Cincinnati, Ohio does not have any extra rent taxes.  

Because of this I have rented two of the apartments to people using them as office/meeting space.

what’s the best way to use OPM to buy my first house to rent out?

I had previously contacted the landlord and he said they had no problems with her, and this was the 2nd property of theirs she has rented, but apparently, that was a lie because I found the court documents about the eviction notices. 

So, I will share my opinion and leave it for other, more tenured investors, correct me.This is my understanding: your goal is to get the property at such price and location that it would make sense for investor (your buyer) to purchase from you and do whatever they want to do with it.
