Determine how much equity is really in the property.

I have been studying REI off and on for years and am now determined to take the plunge.  

All I had was a lot of determination and a supportive girl friend (whom I am married to for 10 years as of this writing).One of the top banks in India gave me a pre-sanction letter that they will finance 80% of the property value or my eligibility amount, whichever is lower.

For single family or small multifamily (up to 4 units) we use recently sold comparables (6 months of less) of similar properties within a mile radius or less, to determine value.  

In terms of hiring a property manager, many property managers are fine managing just 1 property (and since you typically pay a percentage of rent it really shouldn't matter to you).If you want to manage it yourself there are a handful of online landlord / property management software's you could use and access your account anywhere with internet access.You will still need someone (either a friend, or, at a minimum, vendors) you can count on locally to deal with any issues that arise when you are out-of-town.

I need to find the best way to determine accurate ARV's for my wholesale properties. 

I am a dedicated individual and determined. 

I believe that first, you need to determine a plan on what type of properties you collectively desire to invest in, and how.  

The first thing I'd do is to try to determine the after repair value of the property (ARV).

I was trained in Internet and Network security and that is a classic example of a scam post.
