This would allow me to raise the rent for the main house a bit over market but I'm concerned usage could get out of control and making my cashflow take an unpredictable hit.Does anyone see other options here that may work better than the two above?

[Redfin]TP: Personal opinion: rent controls and/or big first-time buyer grants are not the answer.

While the financing and small entry price sound great, you are locked into their ecosystem with very little control.

The tenants have no control over how long the actual processing takes between the banks.

As well as Sellers simply are not informed of the risk of devastating impacts to their credit scores and what equity they may have had in the property if the transaction fails.For a well capitalized Investor and or company and a fully informed seller these can be structured as you note with a Wrap that keeps the seller with  some control or ability to get the property back.

I still need to learn to control my emotions better. 

We're able to crank out mods regardless of weather, have all of our inspections scheduled like clockwork, and control the timing of production with the site work. 

Hi All,I've used Launch Control for a few years, but the system has been down for a week and a half due to TCPA issues.

If you’re the owner of all 5 units you have control.

What works well for me and my investors is Launch Control and Batchleads.
