DSCR loans for 1-4 Units have been in the low 5s-high 4% when rates were very low overall. back a few years agoThey tend to lag behind conventional mortgages, but have stayed stable these lasts few months.

Do the math now, and if it makes sense under the current high rates than you will most likely be fine down the line. 

It's saved me many times during our Flip projects with bad guys trying to break in especially when you bring in your high valued appliances or tools. 

So add 0.25-0.5% for a high LTV, another 0.625% for 2-4 unit and 1.0% for high balance (I assume this falls into the high balance category) and you're right around the rate you were quoted. 

It all depends on the age and quality of the mobile homes you are considering, and your local market.

The other considerations noted by other posters are valid, but when you weigh them against the high risk of extended vacancy, ending at the beginning of winter is to be avoided at all costs.  2 months of added vacancy is a 16.6% loss to annual income. 

I am wondering with what high population growth with this town and the area around it if it is a good start to purchase a townhome that I would be renting out.If needed any town within a 100 mile radius of there I can venture out to.Thank you!!

Sorry, but with so many questions, this scenario stinks to high heaven.You will be lending in second position at best.

Then the lender will borrow you the $200k at a very high rate hoping you fail to make payments. 

These also tend to be higher quality areas with higher quality tenants for people who are renovating their own home or any other reason.
