You just need to establish a proper system to track everything for the rental property so it will be easier comes tax season and also if in case you wanted to analyze how your property is performing. 

It can be pretty flexible depending on how you establish the entity.I lean toward Texas LLCs for their low annual costs and maintenance requirements, but there are several great options.

I have established one funnel so far and it has allowed us to have 635 leads with phone numbers, 97 replies, 13 house visits, 2 contracts and 5 other bids in the first 35 days.  

If the seller is not cooperating, I suspect something's going on.All wholesale deals require that you first establish a rapport with the seller. 

You'd have to establish a complete team there first, then find the properties to fit this scenario, then...all remotely.  

The biggest thing is to get started and get established so that when the market changes and there are great deals everywhere you are ready to take advantage.

Regarding property management fees, I would estimate about 9-10% of rent plus a tenant placement fee for a well-established company.

If you can establish a good relationship, they may even send referrals your way when you're ready to develop the park.

Once established in these deals did that income provide a baseline to become an investor? 

I wouldn’t do the extension just yet wait to get that property established the way it is first then maybe down the line do it.
