I bought my first home using the VA loan for 0% down.

I see so many assumable loan which seems like deal, but I am unable to take it as my DTI is high due to primary property etc. 

Sounds like a hard money lender that wants to take a property from you when you default.There's a lot of issues here starting with a guy that will loan you money and once it gets difficult wants you to abandon ship- red flag.There are a lot of unknowns here but trying to dump it seems like a 100% guarantee to lose money.

I capture different formulas for buy/hold, rehabs, loan costs, material costs.I made one excel workbook with several different sheets.

My only other bills are phone, insurance, gym, and student loan.

I have a $375K  2.5% 15 year loan, paid off in 8 years.

Does having the capacity to pull a business loan or business credit card benefit strategy in any significant way?
