As others have said, the location is a big factor in MTRs, but so is the clientele you are going after.

Other most common factor: Family Size increases due to marriage or having a child. 

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Not saying it's impossible, but the faster you want/need it to happen, the more risk you'll expose yourself to to get there.The massive elephant in the room is: What amount of income do you need to replace? 

A local couple who’se combined income is 300K and who sponsored the family’s immigration to US is willing to be co-signers for the family of 5.I am thinking that Party2 will put more miles on the house and may be harder to deal with in case of any complaints or eviction, though I am not an experienced landlord so I am not sure what are the factors to evaluate or what all can go wrong?

That 95% makes sense as an appreciation return, but for true CoC, you’d need rent income factored in.

.• Use some equity from the sale to make this transition smoother.I’m torn between maintaining our current home as an asset and buying  a new smaller house to use as a rental after we move back in versus simplifying and focusing on a single upgraded property Considering factors like market trends, potential equity growth, and quality of life, which path do you think would be most beneficial?

A replacement cost should factor in depreciation.Airbnb knows exactly what they are doing when the scam hosts by not paying 100% for repair costs. 

Several factors indicate the company is not that concerned about efficiency or ease of customer process: the website, a process that seemed to focus on one issue at a time instead of all issues at once, and consistently poor communications and lack of common sense from the loan analyst we were assigned.It started off very well with the initial point of contact, Austin Lornson, who did a fine job of explaining the general refinancing process, responding quickly and thoroughly to our questions.

If you’re looking at retrofitting to separate heating for each unit (like furnaces or mini-splits), you might be looking at a higher upfront cost, but it can shift utility expenses to tenants and improve your NOI.I’d factor in boiler age and efficiency when analyzing deals and if it’s near the end of its life, negotiate a price reduction or a credit.
