Quote from @Eduardo Perez-Borroto: Since the HELOC was not used on improving the home you cannot deduct the interest, nor use that to offset your capital gain.Would adding a battery bank system to my solar panels count as home improvement? 

I recently came across 1 acre asking for 314k in a very good residential and growing location, so the current owner has added 4 manufactured homes with 4 electrical meters, 4 septic tanks and only 1 water meter for all 4 homes, the homes are sitting on partial slab and partial pier & beam, he also added 2 storage sheds approx. 380sqft with the intention to make them ADUs they are still only the shell so I would have to get those ready to live in, so currently the 4 manufactured homes are being rented and bringing in 2800k a month, 3 of the homes are needing some TLC which could increment rents and possibly get me at 3600k a month, also being a 1ac lot this still leaves about 12,000sqft of raw land where you could build etc.So that is on the good side now the things I did not like so much, the lay out is poorly executed to where it makes it looked crammed up and not professional but it could be fixed.Another is that in reality there is only 4 livable units so that qualifies under a conventional loan but since they're are 6 units on the property the banks are wanting to take it as a commercial so we would have to move out the 2 storage sheds out in order to close as conventional.Another concern, technically you are only allowed to have one manufactured house or single wide in your property according to what I know but I know it could change according to zoning which I will investigate, so my question is has all this been accounted for and if so how can I verify it so it wont leave me in a bind further down the road, I currently asked my agent for the appraisal of the property to see if that might verify.Any recommendations?

First, banks do not prefer W2 income over 1099 income at all.

I bout one in 2019 and it has turned into a gem for me, but at the time, it would not have been 1.25 1.25x is a very common DSCR for a bank.

I’ve done some research and have found that some banks will allow the seller finance portion from the seller to go towards the down payment of the loan, is that true?

So far everyone that has predicted rate drops have been wrong so I wouldn't bank on it. 

He is very good about deductions on tax returns so his income looks negligible and of course banks wont talk to him about loans.

if they are pressuring you like this.PLEASE watch the American Greed Episode on Remmington Financial  .not saying these guys wont or don't fund of course.. but when I do my deals with my banks its common that I pay for the phase one and the appraiser directly..  

I ran my own custom proforma for a bank loan using the asking price that would generate a cap rate over 10% and CoC just under 20%.

He had about 10+ units, and when I tell you he was making bank, he was making bank!
