The new investment earns $24,000 a year, but the mortgage + the equity loan cost will be $22,332—and that’s before you account for taxes, insurance, maintenance, capital expenditures, vacancies, etc.

You could consider doing a cash out refinance of your current primary as an investment property with a dscr loan.From there get a low cost or zero down loan for your Primary.Use the proceeds left from the refinance to get your next property.There are so many different strategies.

I have the capital for a down payment and holding costs for a year but am struggling to find a lender who does not require a first-position lien on the home (the seller does not wish to subordinate his lien position).It has occurred to me to seek a partner-investor who would profit share with me if I was responsible for renovations, as I’m an experienced and licensed Residential Contractor.

I'm trying to start my own books in QuickBooks to keep track of acquisition costs, depreciable assets, and other items that are not tracked in my PM's Buildium books.

@Marc ShinMake sure to double whatever they tell you it will cost and take 2x as long and then have someone to come repair all the shoddy work that was done.Hopefully you have working bathrooms otherwise you may have some surprises hidden behind your walls

Properties in this location may vary in age and upkeep, impacting maintenance costs and potential rental income.
