Some may be issues you need to resolve others may be irrelevant and you may need to reduce your ear's availability.

My mindset was also, then as long as I believe all can execute, I will shop the best rate when I have a deal and am looking to price lock.

Paul,...If you're going to wholesale like a professional, only pursue deals that are worth Cash Buyers' time (target for 60% ARV if you're not confident about estimating repairs)Some wholesalers aim to lock up as many houses as possible and then walk away when their 2 cash buyers won't buy [bad] deals.

Plus, they have a sweet deal with rent, especially being locked in for 2 years, so they wouldn't even want to leave...

You will need to be on your toes at all timesYou will run into set backs (often)You will need to evict peopleYou will need to throw families onto the streetYou will make children homelessYou will have your house damagedYou will need to hire a team of highly skilled people to be your eyes and ears on the groundYou will pay a premium for services provided on your real estate portfolioYou will be harshly judged by those outside of the industryYou will need to make decision based on the best interest of your business and not your feelingsWorks out great for some.

Also  the fact that you have another set of eyes and ears working on your behalf and have your best interest in mind when selling or buying for their client 

I'm in my last steps to lock up financing (conventional) on my first investment property - final inspection was this morning and am discussing options with my lender.  

The easiest way to get them to either shut up or act is to have them put down $5000 of their own money to lock them into purchasing the contract.

I locked in for a 30 yr fixed at 5.375% on my SFH rental.Thats sounds about right.

Or if you have any recommendations, I'm all ears.
