We are about to close on our first sale (approx $7500 profit) & I've come across a landlord who's retiring.

I know which is very high, my property is listed as non residential as per water company since meter is 8in, currently I am paying as a landlord full monthly water bill and all my profits this bill is eating.I ask the water company my property has submeters if i make those active is the water bill going to reduce by making the property as residential?

Use asset-based funding, such as private lenders and commercial lenders - those who loan money based on the value of your properties, their profitability and your credit but not your income.C.

If you own a 2 flat or larger building you can make a great profit using Airbnb.

I would be profiting about 200-300 every month.

I've now sold off all of those at handsome profits. 

Also, they don't get as excited about REI loans, as they are more typically looking to help the Small Business Owner get off the ground (e.g. a Donut Shop, or Lavette's Account,...) at least that's what their rep told me.As for that as for that being a REI strategy, it's viable as long as your numbers are solid and you can profitably repay the loans. 

Tax free profit is sounding pretty good but that's obviously a 1 time thing and we already have cash sitting on the sidelines waiting for the next project.Thoughts and ideas would be much appreciated.

Split the profit.

That is, agree with a fix and flipper that the fix and flipper will fix up the place at their expense, sell it, and then the fix and flipper will split the profits with your parents.
