I think it would be beneficial to set up your own management company to manage your assets.

We designed our company Winnow to be a huge time-saver. 

I’ve built a solid network of contractors, hard money lenders, conventional/DSCR lenders, and property management companies that serve as my trusted boots on the ground contacts in Memphis.

This idea dc is a company town isn’t really true & the company isn’t going out of business, 20% of the workforce is federal government, if they cut 25% of the federal workforce it would be 5% of the region and of course the vast majority are of these people would get jobs in the private sector, not to mention the government will probably have to rely more heavily on government contractors to fill gaps where the cut.

This will help you close deals faster.Focus on marketing and lead generation to find motivated sellers—direct mail, driving for dollars, and online marketing all work well here.Know your numbers—being able to accurately assess the value of properties and make solid offers is key.Network with other investors and professionals—attend local REI meetups, connect with title companies, and build relationships with hard money lenders.Feel free to reach out if you ever want to chat more or exchange ideas!

Question:  Does your company do the nuclear gun-type tests to determine if lead is present? 

How do I go about finding the best banks or companies to get pre-approvals and is it worthwhile to get multiple?

My company for my personal house covers my STR very reasonably.

Some other "adventures" I am looking at - the existing tenant is section 8 and the current property management company likely will not continue management. 

for double closing you would need your funds to buy then sell it to end buyer at premium. there are transactional funding companies that can lend the cash for a fee.
