A client can also close on a new property in less than 45 days so no long closing or pre construction risk. 1031 exchanges are easy to fulfill with our model. 

(but again, I feel this should be part of pre-investment due-diligence).

I’d appreciate some feedback on my current approach and advice if any.Here’s what I’ve done so far:Pre-Approval: I’ve secured a pre-approval amount and interest rate from an online mortgage lender.Property Analysis: I’m using the mortgage and STR calculators from BiggerPockets to assess the financials for potential properties.Neighborhood Research: I’ve been exploring different neighborhoods using Niche to get insights into schools, safety, and livability.AirDNA: I’m considering subscribing to AirDNA for data on occupancy rates and rental income estimates.Questions:Is AirDNA worth the investment for STR data?

Back in the day when I sold rural ranch lands pre google earth you needed to be able to read and understand USGS quad maps and a compass and understand from certain points on the ground you had compass declination's just like when your flying. 

I have already been pre-qualified for a loan. 

(you may want to pick out several based on different lot situations)Based on your plan you should be able to get estimates, You can either go to builders with their plans and ask them their cost to build pre sq.ft. or sq.m, or you can get actual pricing based on your plan. 

@Tanner Sortillo- thanks - I would have the new investor get a solid idea of financing options and for them to get formally pre-approved for a hypothetical scenario. 

Caught the flag on the first sentence "given the loan terms verbally" - Pretty much all the "reputable" DSCR Lenders will give out a detailed term sheet / pre-approval letter / LOI (many different names but same thing) outlining terms and approvals early on in the process - the good news is that if you haven't closed yet you can still switch lenders and see if you can secure your original terms - also good news is that the appraisal, while likely ordered by the lender or broker is in your name and your property, so you can likely transfer it to the new lender

In your situation, when the time comes you think you are ready to purchase, go to your local bank and tell them you want to get pre-qualified.

Buy BP's books on creative financing, zero down, subject to,  pre-forclosure, even short sales.
