I can figure the math for the profit margins once I get the estimates, I'm really just trying to figure out if the addition of the driveway really adds a significant enough increase to the value of the property to make the investment worth it despite the rental income?

I do wonder if I leads to more inventory though, I have for instance another client that this 2.5% might be the difference in deciding to list or not, for sellers without a lot of equity that 2.5% can be the difference between writing and check or not, which in addition to some people not having the money to cut a check is also a huge psychological barrier, there are probably even some people on the margins who have in thier head they will only sell if they can net 100k in profit or some random number like that.

House passes bill to ban the app by a wide bipartisan margin.

Depends on loan type and will vary lender to lender too (especially when comparing retail and broker), not all have the same margins.

Professional builders have a profit margin of 10%.

If they do consider market rates, that means I have a huge margin (my basis $705K) and I can pay any price to buy out the remaining 2 units?

Yes indeed mate.I probably would have fixed the rate also but "underwritten" the deal from a worst case rate scenario like I would do with SFH if financing.I'm not versed in large multifamily deals and would love to learn more.I think I could really do some "damage" in the field because I own and run a property management company and we run a tight ship that's very well optimized from an automation aspect and affiliate fee structure standpoint.So my bottom line for example buying a 50 or 100 unit would be much safer/higher due to in-house PM and "working" the margin.

Do the tax advantages go unchanged, or do they fluctuate with the profit margins?

His average contract value is around 15-20k and his profit margins on these jobs are roughly 50%.I don't have an agency or any sort of business that provides this service.

Property management is a very low margin business.
