Be patient and stay focused.   

@Sakshum Kulshrestha The key to the rental license in Philadelphia is ensuring the properties zoning allows the use.

You could certainly reach this demographic, but it could also cost you substantially more than the return.For the money, your best bet is probably a dedicated website for your property with the key words that you want to convey.

Highly recommend (I require) collecting first month's rent prior to handing over keys.

As for building trust with sellers, communication is key.

You cant view a lot of FL probate dosuments directly from the recorders site but you can get the key people (petitioner/decedent) then combine with the case type (summary vs formal probate admin) then look through property records to see if  they own property and whether there are encumbrances.

(key piece of the story) And where are you/the property located?

Proof of concept seems to be a key part of your strategy starting off.   

I'm from Toledo and know most of the turnkey guys. just make sure to buy later than 1950. don't get the knob and tube and plaster and lathe and cast iron sewer lines. understand that most markets that do turn key or section 8 are going to never appreciate like Cleveland or Toledo or tertiary markets like Akron or Cleveland.

Questions they will have is who is the owner, what experience do they have, is their key person insurance against them etc.
