If you don't mind me asking, which loans do you typically use for house hacking? 

For most DSCR loans, down payments are typically around 20-25%, depending on the lender and the property type.

House gets foreclosed on when a borrower is not paying its debt obligations - typically its mortgage.buying foreclosures is not for the faint of heart as you have no idea of the interior of these properties lastly while it can be beneficial also realize if there are a lot in an area those homes are the new comps when trying to sell so it lowers home values in an area 

My vote is if you are going to continue to buy, you need to utilize leverage.

It is a great deal for the silent investor as they typically make 50% - 100% COC in less than a year.

Current HELOC rates are typically 8-10% depending on your credit and lender, though some banks offer promotional rates.

Typically a tax foreclosure is first position lien.

@Polat CaglayanI've never seen a formula but here is a general rule of thumb for multifamily:The class of an apartment refers to the quality of the building, which can be determined by a number of factors, including age, location, and condition: Class A: These are the highest quality apartments, typically built within the last 15 years.

Plus you can't typically get conventional financing because they want to finance to a person, not an entity.

So you would spend around $25-$30k a month (this was 15 years ago) on police details and require union gate and non union gate if you had non union workforce as well.In DC area, the utility providers are a huge challenge, whether getting permanent power, or water/sewer service etc - good luck.
