In addition to what's been said above, the invoice should clearly state the address where the work was done and your company's name.

We were at a loss for how to get cash to purchase additional property, and are considering taking out a mortgage on the duplex.

Account Closed I'm maxing out on the pre-tax contribution amount every year, my employer matches 5% of my pay contribution, the markets would have to have an average loss of -15% every year for the next 25 years for me to end up with a balance that consist of just my payroll contributions.I think those numbers on the charts you're listing are for people working low wage jobs and probably contributing a few hundred dollars a month to their 401K plans, in that scenario putting 200-300 dollars a month away is something that will help but probably not going to be enough to live on in retirement.Like many have mentioned on here you have to be diversified with Real Estate and various aspects of the financial markets, If you're heavily positioned in one market or the other with no diversification you'll end up in the average pool of investors.

@Nadir M.Two additional thoughts:1) A central boiler is a cost trap for owners.

I would appreciate hearing from other lease option folks about how they explain this aspect of lease options.

In addition you'll have to make the monthly interest only payments.

There is additional reserve requirements when buying more than 1 unit, so get up to speed on those so you are prepared to have those in place at the time of closing your loan. 

These are professionals with additional training and a stricter code of ethics.

I have my own construction company in addition to my real estate business so my situation is different than most as I have the entire scope of work completed by my own crews aside from a few items like plumbing that we sub out.Before that, I acted as the GC as owner builder and hired each individual sub.

@Edgardo CorreaThe most important aspect of wholesaling is the contacts you have in this business.
