Additionally, buying in bulk can lead to discounts, which helps in reducing overall costs.

We only require a cleaning on move-out but we give our clients the option to require mid-stay cleans since that would be an additional expense for them. 

You asked about short-term rental property demand and mid-term rental property demand in other areas besides yours and thoughts on managing these properties.First off, short-term rentals are a great property class to own, especially if you "materially participate" with 500 ours in the management of your property for the IRS to consider it an active investment and able to write down your active or W-2 income with the expenses, bonus depreciation, and cost segregating the property for additional depreciation to reduce your income taxes.There is short-term rental demand in many communities in Michigan because we have so much coastline and natural beauty as well as university, business, and hospital stay demand.

A realistic timeline is 45 days for approval then an additional month for inspections/ reinspections and move in.  

Separate “must-do for safety/function” from “nice-to-have to increase ARV.”For BRRRR, the only things that must be done upfront are the items an appraiser, inspector, or tenant would flag as functional or safety issues, plumbing, electrical, bathroom addition, paint, etc.

The bank I typically use for flips will do me a rental loan for 15% down of purchase price and then add into the loan the additional reno expenses as I need them so I am not out of pocket any further. 

Seriously though, they will want additional details.There are hard money lenders who don't require all of that data but they want you to put down 30% of the money to buy and they will provide 70% at a high interest rate.

In addition, I'd go to some local networking groups to meet other investors now.

You can terminate the current lease by mutual agreement and issue a brand-new one that includes the additional adult as long as the new person is fully screened (credit, background, income, rental history, employment, etc.).

If you hire another layer of management they are going to take their additional 10-15% for their time and expertise (although on a 10-15k rehab that isn’t much and probably worth it)We have clients do BRRRs often, but not in 90 days and they still have a few dollars let in the deal when said and done.
