I was able to rent out the house in 3 weeks and for $2050 / month which covers all the renovation loans and mortgage and cashflows $360 / month.

I wouldn't mess with a good loan on the one you have.If the existing loan is a high rate I'd think about refinancing. 

Of being away from your wife and kids for a year, you are also "spending" an extra $19k to qualify for your loan.

I have taken a "loan" against the 401k rather than withdrawing money.

The property was acquired through a hard money loan that is expiring soon and I still have not been able to rent a single unit.

Some documents include loan application, credit auth, purchase agreement, recent bank statement, property insurance, title documents, entity documents and renovation budget. 2) What interest rates should I expect for Fix & Flip, renovation, and BRRRR properties?

You get that back if you sell, but if you keep it as a rental it takes 153 months or 5 years to break even on your down payment alone.https://www.redfin.com/IN/Indianapolis/1515-E-Kessler-Blvd-Dr-46220/home/66981054ARV / Sell Price$235,000We Calculate All CostsPurchase Price$152,750 65%Closing Costs$2,000Rehab$30,0006 Months Carrying Costs$9,114Real Estate Selling Costs$14,1006%Other$0Other$0Total Rehab Costs$207,964Now We Calculate ProfitARV / Sell Price$235,000Total Rehab Costs$207,964Gross Profit$27,036IRS Tax$4,05515%Net Profit$22,981Per month profit$3,8306Loan Down Payment$30,55020%Loan Amount$122,200 80%Loan Cost per rmonthPrincipal & Interest$8137%Prop Taxes$321Insurance$168HOA Fees$0Monthly Payment Costs$1,302Monthly Payment 1$1,302Monthly Payment 2$1,302Monthly Payment 3$1,302Monthly Payment 4$1,302Monthly Payment 5$1,302Monthly Payment 6$1,302Utilities for 6 months$1,302Total for 6 Months$9,114

(IMO) Loans with non-fixed rates--those things should be outlawed.Just my 2 cents.

I'm not a big fan of adjustable rate loans.

So - my question - my current mortgage holder gave me two options to refi and remove my wife's name from the loan both keep the current 4.x% rate but one can be done within 45 days and the loan starts again at 30 years.The other option, an assumption process, takes 4-6 months, retains the 4.x% rate but keeps the life of the loan at the current 24 months.I'll be rolling a HELOC into the loan.My question is:  the longer term of 30 years will lower the monthly outlay a little bit and speed the process of getting my wife's name off the loan.
