@Dan Schweit and @Jaysen Medhurst There are some incredibly aggressive commercial programs out there for 1-4 units right now that will cash out up to 75% into a 30 year fixed term without previous rental history other than a signed lease and proof of deposit! 

Also Alexander Felice wrote an article about the Delayed Financing Program in which you can refinance sooner as well. https://www.biggerpockets.com/blog/work-with-lenders-brrrr-method

@Liosbel Gonzalez the 210 day is VA specific if using the IRRL program according to the lender.

if its not above 10 or amount you cant manage, i wouldnt worry about using certain programs because thats just extra expense.. 

Thanks - Depending on the type of project you are talking about there are software programs for estimating residential and commercial construction costs but they are not very useful especially this environment of rapidly rising labor and material costs.

So I don't actually do section 8 or assisted housing programs for that reason.

@Alfred LittonWe have a great program available for rental properties. 1 million liability, replacement cost, water damage, and $2500 deductible.

Glad I found BP, too, because I was just about to drop $1k on a mentor program program with Phil P---ski...

I'm curious if underwriters have any algorithms or programs that take care of this automatically based on a few inputs or if they largely pull comps manually? 

The programs we have are called the "Way Finder" & the "What If Simulator".
