Quote from @Dave Skow:
@Damon Aniton- thanks ...definitely get a formal pre approval in place with a lender in order to find out for sure what the maximum loan amount will be and what rental income that will be usable for your present rental and also for the 3 units you plan to rent on the new 4 plex.....also - fyi - if the present loan is a VA loan - buying another property using another VA loan might be an issue - good luck
Yea like all things VA there are "loop holes" and complicated math to it. Essentially in 2020 they did away with loan limits, on the first property. They only exist if you buy a 2nd primary residence. So essentially they will take the calculation of what you spent on home 1 and VA math it to determine how much eligibility you have left to buy a 2nd primary residence.
Easiest way to explain it is divide the purchase price by 4 and that is your eligibility number. Then find the loan limit for the county you will buy the next home. Divide that by 4. Then subtract the entitlement amount from your first purchase. And if anything is left over youtake that number and multiply by 4 and this is your max purchase amount with 0 down or PMI again. Anything above this number you pay 25% down of the difference.
