I don't really have enough information from you to give you very specific advice, but I can say that if there is any room in the rent, it's probably only a couple of dollars PSF which isn't going to drastically change your overall monthly nut to crack.

We manage 37 doors with that costs us a few dollars per door per month with no surcharge for ACH payments and we get next business day credit for those.  

The value resets, and the dollars you take out will determine the new equity split at that point in time.  

Once the understanding of the complete process is experienced, (and one gets the bumps and bruises to show for it) then it becomes so much easier to plug in dollar goal numbers.Good luck!!! 

It is the last buildable lot in the middle of 1.4 million dollar homes. 

Look at real estate professional status closely, this area of the tax code(section 469) is where I think If you worked with the right real estate-focused accountant you could save 100s of thousands of dollars. 

Try focusing on the growth in dollars rather than the growth in number of properties. 

This can be confusing to people who will inevitably say, "Why did my taxes jump by thousands of dollars!?"  

They collect your rent, apply late fees,  deposit your monies into your bank account, market your properties, track expenses, screen your tenants, etc for just a few dollars a month per door.  

Wholesaling can be done without any money up front by driving for dollars, facebook posts or looking at MLS postings.
