There are products specifically for rentals, but I feel like using this approach will work best for me in the long run as I grow because its generic and I can get any bookkeeper to work for me.

most lenders  will  utilize the  schd E rental income average  method  for  including rental  income for  qualifying ...if the  proeprty is  recenlty  purchase the  vacancy factor  approach is used 

Especially w first few deals, the sweat-equity partner may only contribute 30% of value, so 30-70 is the arrangement, especially if it's a short-term JV...I think we hear the 50-50 talk from established investors who have built a long-term relationship w investor-partners.Yes, we could get into the minutiae of tracking the dollar-value the "worker" brings to the table over time, which I guess is the spirit of the "mini-mortgage" approach: Estimate the value of their sourced-deal if wholesaled; set an hourly wage for office-work/time spent renovating; charge a leasing fee for tenant placement and 10% of rent or whatever each month for PM moving forward... 

I like this approach as its the slow and steady method to meet my goals. 

They may just use income approach or the bank may do their own appraisal since the bank will likely hold the loan. 

Right now trying to fill two positions, one is hourly at $80/hour and the other is a salary position which including expected bonus will approach the quarter million dollar range in 2022.

Wondering if there is any advice or recommended resources for learning how to approach the whole process including namely all the due diligence needed before we pull the trigger on a deal? 

You should approach it from that standpoint VS you are owed a favor.  

I started out by running Spartan races, and cleaning up my diet, to eventually transitioning into a bodybuilding and powerlifting approach on things. 

I guess I'm looking for what approach an experienced investor would do in my situation, or if I should wait and just continue to build my knowledge until I'm out of school.Looking forward to responses!
