I have a LOT more rentals than you buy most have mortgages so the cash flow is minimal. 

If I'm buying a property in which I'm going to do minimal work cleaning and gutting it and I only own the property for less than a week, will lenders still lend me money for this really short period of time?

Make sure it is convenient for all those effected by it and needs to have minimal distractions.  

What about your time wasted and time that your property is sitting vacant?

My expenses would be very minimal since its newer.

Once we work together on a deal or two odds are slim i would waste your time or mine by filling out the form on every property. 

If you're putting in minimal time and effort then sure anything is better than nothing, it'll just take significantly more than that to seriously scale it.

They can get a loan letter to you that states the average loan closing time and the maximum amount that you qualified for.Another thing you might do is to find your office location that is convenient and has a minimal of distractions.  

If it only has one bath - and you're not adding another, then carefully plan your bath remodel so the toilet/shower is out of commission for a minimal amount of time.Keep one room clean.

As a realtor I have seen so many decor jobs painstakingly done by somebody's wife that were a total waste of money and ended up getting gutted upon closing.
