For conventional and DSCR lenders, it’s pretty typical that refinancing is based on the current appraised value or ARV, not just the purchase price, and many require some seasoning—usually anywhere from 3 to 6 months.Refinancing at 70-75% of just the purchase price with little to no seasoning is uncommon with conventional or DSCR loans.

We've hosted a wide range in our units in Columbus, corporate relocations and travel nurses, but a big chunk of our bookings come from traveling tradespeople like electricians, welders, and pipe fitters working on regional infrastructure projects.We've noticed:Tradespeople tend to book 8-24 weeks at a time, sometimes longer if the job extends (not uncommon).Insurance placements are generally higher paying but come with more red tape and longer setup times.Travel nurses are steady and reliable, but in some cases, price-sensitive.Corporate guests vary depending on industry.
