If it's a financially tight deal or you don't have the money to properly support and maintain the property, especially if you don't have much "skin in the game", it's a riskier proposition for the lender. 

IE if you really run the numbers that tight.. like you want to know to the decimal point what your COC is from year to year.  

The 45/180 calendar day deadlines start running with the closing of the first relinquished property. 

Agreed HML underwrite pretty tight these days.. 

A lot of good deals are purchased from such Seller’s that don’t run a tight ship- there may be plenty of meat on the bone to increase rents or renovate and sell at true market value for a well kept property.

He was mentioning that if I take on multiple mortgages it will lower essentially my buying power because it will make my debt ratio profile tight and effect my buying power for my family home.

The puchase/rehab numbers you layed out with the ARV you mentioned seems very very tight.

Good advice on getting #1 under our belts and just sitting tight for a bit.As far as Mashvisor goes, the tool provides analysis of both STR and LTR, although you definitely have to check their numbers on estimated LTR rent rates. 

BRRRR'ing (haha) a property is tight in this area and will prove to be difficult but not impossible.

@Caleb Johnson I agree that it sounds like a tight deadline.
