By showcasing the mutual benefits of my offer, including a quick and seamless closing process, I was able to secure favorable terms that aligned with my investment goals.

I only have savings accounts for my security deposits.

Wanted to know if it's possible to send a tenant to collections after a move out/ evictions for additional charges the security deposit didn't cover.

No security deposit either. 

You need to look for a Securities Attorney (not a real estate attorney)As @John Sayers mentioned, you can get ownership with a GP by doing other things, like bringing the deal, asset management, data research, etc.

Just trying to find out how to secure remaining 20% for seller

I am wondering if the interior stairs are typically removed to allow for more sq ft in the basement unit as well as greater security  between the two units?

However, it seems like it might be too late to secure tenants for this school year.

Additionally, unrelated business income tax (UBIT) might apply if your property is financed.One option to consider is partnering funds from multiple accounts or other individuals to share in the investment, which may avoid the need for difficult-to-secure non-recourse financing.

Others 15 yrs, etc.So we depreciate a portion of the asset costs faster.We do the study and get dollar amounts assigned to different parts and different schedules to front-load depreciation.Now you can get 5 or 6% of the value as a deduction in the early years...But wait... there's more.Bonus depreciation allows you to deduct a certain percentage of cost in the first year an asset is put into service.Anything that is on a schedule of 15 years or less...So the doors, sidewalks, HVAC, walls, latches, curbs, security, gates, etcA % of this stuff goes in Yr 1.For years 2015 through 2017, first-year bonus depreciation for these items was set at 50%.It was scheduled to go down to 40% in 2018 and 30% in 2019, 0% in 2020.But then the Tax Cuts and Jobs act moved this percentage to 100% from 2017 to 2022 and 80% in 2023 and 60% in 2024.Its not uncommon to allocate 30% of an asset cost to items that can be depreciated on a 15 year or faster time frame.So now 60% of that 30% of your asset's cost can be depreciated in the first year, excluding land.Pretty great.This is how real estate owners, investors, and operators make millions and pay very little in taxes compared to W2 employees.They pay even less and can offset other types of income if they are an RE Pro.
