At that tax sale, there is basically two year lag before you can resell it...in the meantime they need to pay taxes and HOA dues. 

Adding closet organization and cosmetic improvements are likely to add another $5k.Thanks, Parris

Their first round effort has produced $42K in 0% funds to use over the next year and I am going to use those to accelerate my purchases and re-selling activity.

I was thinking they could take care of things like research options for insurance, find contractors for repairs on rentals, intake tenant maintenance requests, assist with finding deals, and organize the documentation for each property.

It seems like in order to make any profit as a developer selling spec homes you have to be a GC so you don't have to pay the fee and can organize the work yourself.

* Resell - I personally had an issue with one of my flips years ago, due to the basic unpermitted work that was done.

Once you get the property most you won't be able to resell for at least a year because the new owner will want/need title insurance and that likely won't be possible as title companies recognize the risks with the whole tax sale process.

My recommendation is to focus on Stick-Built, Brick & Mortar property versus Mobile/Manufactured, main reasons; 1) Investor appetite, 2) Appreciation factor, 3) Re-sell value, 4) Future buyer/investor appetite.

The organization consists of over 700 agents with relationship building being the bedrock of our company. 

Leveraging your $300K into multiple rental properties where you earn in 5 ways on each property is going to help you get to your 7-10 property goal faster vs waiting for rates to organically drop.
