Do not cut any corners to make something look better.Always do the math analysis and try to look at the prospective properties before you make an offer or at least have a clause in the sales contract that will allow you the time (about15 days) to make a detailed inspection of the property and possibly back out of the deal without a penalty that will hurt you too much.  

My initial plan is to get the extra cash I need for building more reserves and down payments by flipping/wholesaling, which I still want to do in order to speed things up.

If you want to discuss personally in more detail, just DM me.JC

You could owe extra fees after the County/city sold some type of tax lien on your property, through their normal collection process.

Which is 20-30k more for just 200 sqft extra.

If you'd like to PM me a few more details, I'd be more than happy to work something out with you.

Everyone is happy and it avoids extra costs involved with using Banks.

This is a pretty involved detailed question but they typically have a few metrics they lend on.
